City

:For alternate meanings see city (disambiguation) A city is an urban area that is differentiated from a town, village, or hamlet by size, population density, importance, or legal status.

Introduction

In most parts of the world, cities are generally substantial and nearly always have an urban core, but in the United States many incorporated areas which have a very modest population, or a suburban or even mostly rural character, are designated as cities. City can also be a synonym for "downtown" or a "city centre". A city usually consists of residential, industrial and business areas together with administrative functions which may relate to a wider geographical area. A large share of a city's area is primarily taken up by housing, which is then supported by infrastructure such roads, streets and often public transport routes such as a subway or a metro rail system. Lakes and rivers may be the only undeveloped areas within the city. The study of cities is covered extensively in human geography. "The city is a human habitat that allows people to form relations with others at various levels of intimacy while remaining entirely anonymous." (This definition was the subject of an exhibition at the Israeli pavilion at the 2000 Venice Biennale of architecture)

The difference between towns and cities

The difference between towns and cities is differently understood in different parts of the English speaking world. There is no one standard international definition of a city: the term may be used either for a town possessing city status; for an urban locality exceeding an arbitrary population size; for a town dominating other towns with particular regional economic or administrative significance. Although city can refer to an agglomeration including suburban and satellite areas, the term is not appropriate for a conurbation (cluster) of distinct urban places, nor for a wider metropolitan area including more than one city, each acting as a focus for parts of the area. In the United Kingdom, a city is a town which has been known as a city since time immemorial, or which has received city status by royal charter — which is normally granted on the basis of size, importance or royal connection (traditional pointers have been whether the town has a cathedral or a university). Some cathedral cities, for example St. David's in Wales, are quite small, and may not be known as cities in common parlance. (See the City status in the United Kingdom.) A similar system existed in the medieval Low Countries where a landlord would grant settlements certain privileges (city rights) that settlements without city rights didn't have. This include the privilege to put up city walls, hold markets or set up a judicial court. In Australia and New Zealand, city is used to refer both to units of local government, and as a synonym for urban area. For instance the [http://www.southperth.wa.gov.au City of South Perth] is part of the urban area known as Perth, commonly described as a city. On the other hand, Gisborne in New Zealand is known as the first city to see the sun, despite being administered by a district council, not a city council. An interesting phenomenon in American English is the generalisation of the term city to all settlements. Britons may be bemused by forms with fields headed, not Town and Postal code, but City and ZIP, even though the person needing to fill it in could be living in a city, a town without city status, or even a village or hamlet. In turn, many Americans often talk of "City Halls" when referring to town halls in quite small European towns and villages. Strangely, even though Americans are well aware that "village" means something smaller than a town, the word has often been co-opted by enterprising developers to make their projects sound welcoming and friendly. The result are so-called villages with 20 and 30-story high-rises, like Westwood Village in Los Angeles.

Geography

Westwood Village, of around 1550. The city is completely surrounded by a city wall and defensive canal. The square shape is inspired by Jerusalem.]] The geographies of cities, both physical and human, are diverse. Often cities will either be coastal and have a harbour or be situated near a river giving economic advantage. Water transports on rivers and oceans were (and in most cases still are) cheaper and more efficient than road transport over long distances. Older European cities often have historically intact central areas where the streets are jumbled together, seemingly without a structural plan. This quality is a legacy of earlier unplanned or organic development, and is often perceived by today's tourists to be picturesque. Modern city planning has seen many different schemes for how a city should look. The most commonly seen pattern is the grid, almost a rule in parts of the United States, and used for thousands of years in China. Derry was the first ever planned city in Ireland, begun in 1613, with the walls being completed 5 years later in 1618. The central diamond within a walled city with four gates was thought to be a good design for defence. The grid pattern chosen was subsequently much copied in the colonies of British North America [http://worldfacts.us/UK-Londonderry.htm]. However, the grid has been used for a long time in history. The Greeks gave their colonies around the Mediterranian often with a grid. One of the best examples around is the city of Priene. This city even had it's different districts. Much like modern city planning today. Also in de Medival times we see a preference for lineair planning. Good examples are the cities establish in the south of France by various rulers. And city expantions in old Dutch and Flanders cities. Other forms may include a radial structure in which main roads converge on a central point, often the effect of successive growth over long time with concentric traces of town walls and citadels - recently supplemented by ring-roads that take traffic around the edge of a town. Many Dutch cities are structured that way: a central square surrounded by a concentric canals. Every city expansion would imply a new circle (canals + town walls). In cities like Amsterdam and Haarlem this pattern is still clearly visible.

History of cities

Towns and cities have a long history, although opinions vary on whether any particular ancient settlement can be considered to be a city. The first true towns are sometimes considered to be large settlements where the inhabitants were no longer simply farmers of the surrounding area, but began to take on specialized occupations, and where to trade, food storage and power was centralized. Societies that live in cities are often called civilizations. By this definition, the first towns we know of were located in Mesopotamia, such as Ur, and along the Nile, the Indus Valley Civilization and China. Before this time it was rare for settlements to reach significant size, although there were exceptions such as Jericho, Çatalhöyük and Mehrgarh. The growth of ancient and medieval empires led to ever greater capital cities and seats of provincial administration, with ancient Rome, its eastern successor Constantinople and successive Chinese and later Indian capitals approaching or exceeding the half-million population level. It is estimated that ancient Rome population exceeded one million people by the end of the last century BCE, which is considered the only city to reach that number until the Industrial Revolution, however, Alexandria population was close to one million at the same time. Similar large administrative, commercial, industrial and ceremonial centres emerged in other areas, though on a smaller scale. During the European Middle Ages, a town was as much a political entity as a collection of houses. City residence brought freedom from customary rural obligations to lord and community: "Stadtluft macht frei" ("City air makes you free") was a saying in Germany. In Continental Europe cities with a legislature of their own wasn't unheard of, the laws for towns as a rule other than for the countryside, the lord of a town often being another than for surrounding land. In the Holy Roman Empire (i.e. medieval Germany and Italy) some cities had no other lord than the emperor. In exceptional cases like Venice, Genoa or Lübeck, cities themselves became powerful states, sometimes taking surrounding areas under their control or establishing extensive maritime empires. Similar phenomena existed elsewhere, as in the case of Sakai, which enjoyed a considerable autonomy in late medieval Japan. Most towns remained far smaller places, so that in 1500 only some two dozen places in the world contained more than 100,000 inhabitants: as late as 1700 there were fewer than forty, a figure which would rise thereafter to 300 in 1900. A small city of the early modern period might contain as few as 10,000 inhabitants, a town far fewer still. While the city-states, or poleis, of the Mediterranean and Baltic Sea languished from the 16th century, Europe's larger capitals benefited from the growth of commerce following the emergence of an Atlantic economy fuelled by the silver of Peru. By the 18th century, London and Paris rivalled the well-developed regionally-traditional capital cities of Baghdad, Beijing, Istanbul, Kyoto and Venice. The growth of modern industry from the late 18th century onward led to massive urbanization and the rise of new great cities, first in Europe and then in other regions, as new opportunities brought huge numbers of migrants from rural communities into urban areas. In the Great Depression of the 1930s cities were hard hit by unemployment, especially those with a base in heavy industry. Today the world's population is about half urban, with millions still streaming annually into the growing cities of Asia, Africa and Latin America.

Modern conceptions

Traditional approach

A universal linear approach to cities has been in place and accepted for a long time. As this approach falls short of explaining a number of aspects of city life, such as the diversity between cities, new ways have been sought. Influenced by post-structuralist thinking a new approach was born: using spatial thinking it is possible to not only fill the gaps, but indeed replace the old completely. Three characteristics have been identified as defining a city: the number of people to area (density), the networks of the city, as well as a particular way of life. None of these characteristics alone is enough to make a place a city. Until recently cities were almost exclusively viewed as part of a single, linear line of development. Starting with the Greek city-state, this linear approach placed each city somewhere, and it was believed that it was only a matter of time until the next stage along the prescript path of advancement was reached. For each stage an exemplar was identified. Step by step from Athens onwards to Venice and London, Los Angeles seemed to be the ultimate stage of a postmodern city. Such an approach regarded a city as a single static entity, which could be studied disconnected in time and space. This leads to a theoretical framework with little connection to real cities, but these were simply seen as less clear examples. In spite of apparent shortcomings, this approach is still very commonplace in respected and popular publications.

Shortcomings

Despite its wide acceptance this traditional approach to cities had serious shortcomings. Firstly, leaving the latest stage aside, it was completely eurocentric. It was believed that every city in the world could be compared with a past stage in the history of one European city. Secondly, there was no real explanation when and how changes occurred, how another stage in the line of development was achieved. There seemed no need to follow the changes of one city, but instead attention was turned to another exemplar. Thirdly, the disconnected view of cities is problematic. It implies that history, culture and connections of a place do not influence a place, which is questionable. Some thinkers argue that a history ignoring connections is necessary incomplete. Fourthly, the traditional approach failed to define what makes a city. It is unclear why one place is regarded as a city while another one is not. Lewis Mumford argued in 1937 for a social dimension, describing cities as geographical plexuses. Finally, viewing cities as a single body misses modern conceptions that there is more than one story to a place. The city of an aristocrat will surely differ from that of a slave. This also reflects a shift away from one single history of the powerful élites (often referred to as city élites) to a multidimensional perception of history. The notion of city rhythms has been introduced to highlight the different aspects of city life... The term city can be used to mean either an area of contiguous urbanization or a particular municipality (an [http://www.demographia.com/db-world-muni.htm area within the political borders of an incorporated municipality]). There is a substantial variation in municipalities around the world. The largest municipality, Chongqing, is approximately the same size as the state of Indiana and contains much more rural territory than continuous urbanization. In most cases, however, the continuous urbanization popularly thought of as the city extends well beyond the boundaries of the core incorporated city.

Modern approach

As a modern approach to cities, urban thinking analyzes various issues that arise in urban areas. It focuses largely upon connections and internal divisions which helps create a better understanding of the dynamics of cities. Using such spatial thinking, it is possible to understand various aspects for which the traditional approach did not provide an adequate explanation. One important aspect of spatial thinking is looking at the connections of a city. Such connections allow one to understand the unique character of a place. Rather than treating all cities the same, places are seen as interconnected through networks of culture, economics, trade or history. So while London and Tokyo are economically linked through stock markets, Graz and Stockholm are linked via the Cultural Capital of Europe. These networks overlap and are concentrated in cities. Arguably this concentration of networks creates a unique feeling of a place. Such networks, however, do not only link cities with cities, but also a city to its surroundings. The notion of a city footprint reflects the idea that a city on its own is not sustainable: it depends on produce from its surroundings, it needs trade links and other connections for economic viability. Looking at networks, it becomes possible to explain the rise and fall of cities. This has to do with the changing importance of connections and is maybe best illustrated with the arrival of Spanish colonizers in America. Within a short time, connections to Madrid became more important than connections to the former centre Tenochtitlán. The concentration of networks in cities can be used as an explanation of urbanization. It is the access to certain networks that attracts people. As various networks spatially run together in a confined area, people gather in cities. At the same time, this concentration of people means the introduction of new networks, such as social links, increasing the creation of new possibilities within cities. Urban social movements are a direct result of this possibility of making new connections. It is this openness to new connections that makes cities both attractive and to a certain degree unpredictable. Another important aspect of modern urban thinking is looking at the divisions within a city. This internal differentiation is linked to the external connections of a city. As places of meeting histories, cities are hybrid and heterogeneous. Hybrid they are as the connections which link places are bilateral, involving giving and taking in both directions. Heterogeneous they are because of the dynamism of cities. New encounters are ongoing processes where social relations and differences are constantly negotiated and shaped, reflecting the unequal power involved. Neither the internal differentiations nor the connections and networks of a place on their own define a city. Internal divisions are caused by external links, while at the same time connections to the outside open up the possibility of new social divisions. Divisions and connections in every city are intertwined, and only by considering both aspects of spatial thinking the complexity of cities is approachable. Immigration illustrates this interconnection of external networks and internal divisions well. The networks concentrated in the core of the city attract immigrants. As they immigrate, the newcomers bring along their histories, bringing new networks or enforcing existing ones. At the same time, their history offers opportunities to identify with or likewise exclude. Division and connection come hand in hand. Rather than attempting to eradicate such tensions and contradictions in the theoretical framework, modern urban thinking – influenced by poststructuralist thought – accounts for both sides. Static universal bodies are replaced by multidimensional networks, allowing for fluidity and dynamism.

Global cities

A global city, also known as a world city, is a prominent centre of trade, banking, finance, innovations, and markets. The term "global city", as opposed to megacity, was coined by Saskia Sassen in a seminal 1991 work. Whereas "megacity" refers to any city of enormous size, a global city is one of enormous power or influence. Global cities, according to Sassen, have more in common with each other than with other cities in their host nations. Bangkok, Beijing, Brussels, Chicago, Hong Kong, Johannesburg, London, Moscow, Mumbai, New York, Los Angeles, Paris, São Paulo, Seoul, Shanghai, Singapore, Sydney, Tokyo, and Toronto are commonly referred to as global cities, however, the term is also applied to other cities. The notion of global cities regards the power of cities as contained within cities. The city is seen as a container where skills and resources are concentrated. The more successful city is able to concentrate more of these skills and resources. This makes the city itself more powerful in terms that it can influence what is happening around the world. Following this view of cities, it is possible to rank the world's cities hierarchically (John Friedmann and Goetz Wolff, "World City Formation: An Agenda for Research and Action," International Journal of Urban and Regional Research 6, no. 3 (1982): 319.). Critics of the notion point out to the different realms of power. The term global city narrowly focuses on economics. Cities like Rome are powerful in religious terms. Additionally, it has been questioned whether the city itself can be regarded as an actor. In 1995 Kanter argued that successful cities can be identified by three elements. To be successful, a city needs to have good thinkers (concepts), good makers (competence) or good traders (connections). The interplay of these three elements, Kanter argued, means that good cities are not planned but managed.

Environmental effects

Modern cities are known for creating their own microclimates. This is due to the large clustering of hard surfaces that heat up in sunlight and that channel rainwater into underground ducts. As a result, city weather is often windier and cloudier than the weather in the surrounding countryside. Conversely, because these effects make cities warmer (urban heat shield or urban heat islands) than the surrounding area, tornadoes tend to go around cities. Additionally towns can cause significant downstream weather effects. Garbage and sewage are two major problems for cities, as is air pollution coming from internal combustion engines (see public transport). The impact of cities on places elsewhere, be it hinterlands or places far away, is considered in the notion of city footprinting (ecological footprint).

Inner city

Main article: Inner city In the United States, United Kingdom and Republic of Ireland, the term "inner city" is sometimes used with the connotation of being an area, perhaps a ghetto, where people are less educated and wealthy and where there is more crime. These connotations are less common in other Western countries, as deprived areas are located in varying parts of other Western cities. In fact, with the gentrification of some formerly run-down central city areas the reverse connotation can apply - in Australia the term "outer suburban" applied to a person implies a lack of sophistication. For instance, in Paris the inner city is the richest part of the metropolitan area, where housing is the most expensive, and where elites and high-income individuals dwell. The United States, in particular, suffers from a culture of anti-urbanism that some say dates back as far as Thomas Jefferson who wrote that "The mobs of great cities add just so much to the support of pure government as sores do to the strength of the human body." On the businessmen who brought manufacturing industry into cities and hence increased the population density necessary to supply the workforce, he wrote "the manufactures of the great cities... have begotten a depravity of morals, a dependence and corruption, which renders them an undesirable accession to a country whose morals are sound." Modern anti-urban attitudes are to be found in America in the form of a planning profession that continues to develop land on a low-density suburban basis, where access to amenities, work and shopping is provided almost exclusively by car rather than on foot. However, there is a growing movement in North America called "New Urbanism" that calls for a return to traditional city planning methods where mixed-use zoning allows people to walk from one type of land-use to another. The idea is that housing, shopping, office space, and leisure facilities are all provided within walking distance of each other, thus reducing the demand for road-space and also improving the efficiency and effectiveness of mass transit.

Town

There is no universal, standard definition of the word town. This is mostly due to the evolution of the English language as an amalgamation of words from many other languages. "City" and "village" came into English from Latin via French. "Town" and "borough" (also "burrow," "burgh," "bury," etc.) are native English and Scottish words.

Etymology of the word and use around the world

In Old English and Old Scots, "Town" (or "toun," "ton," etc.) originally meant a fortified municipality, whereas a borough was not fortified. But that distinction did not last long, and "Edina Burgh" or "Edinburgh" - modernly called a "city" - was a fortified "town" from its founding. In American English, a town is usually a municipal corporation that is smaller than a city but larger than a village. In some cases, "town" is an alternate name for "city" or "village" (especially a larger village). Sometimes, the word "town" is short for "township." In general, towns can be differentiated from townships, villages, or hamlets on the basis of their economic character, in that most of a town's population will tend to derive their living from manufacturing industry, commerce, and public service rather than primary industry such as agriculture or related activities. A place's population size is not a reliable determinant of urban character. In many areas of the world, as in India at least until recent times, a large village might contain several times as many people as a small town. The modern phenomena of extensive suburban growth, satellite urban development, and migration of city-dwellers to villages have further complicated the definition of towns, creating communities urban in their economic and cultural characteristics but lacking other characteristics of urban localities. Some forms of non-rural settlement, such as temporary mining locations, may be clearly non-rural, but have at best a questionable claim to be called a town. The distinction between a town and a city similarly depends on the approach adopted: a city may strictly be an administrative entity which has been granted that designation by law, but in informal usage, the term is also used to denote an urban locality of a particular size or importance: whereas a medieval city may have possessed as few as 10,000 inhabitants, today some consider an urban place of fewer than 100,000 as a town, even though there are many officially designated cities that are very much smaller than that.

Australia

In Australia, the status of a town is formally applied in only a few states. Most states do define cities, and towns are commonly understood to be those centres of population not formally declared to be cities and usually with a population in excess of about 250 people. The creation and delimitation of Local Government Areas is the responsibility of the state and territory Governments. In all states and the Northern Territory each incorporated area has an official status. The various LGA status types currently in use are:
- New South Wales: Cities (C) and Areas (A)
- Victoria: Cities (C), Rural Cities (RC), Boroughs (B) and Shires (S)
- Queensland: Cities (C), Shires (S), Towns (T) and Island Councils (IC)
- South Australia: Cities (C), Rural Cities (RC), Municipalities/Municipal Councils (M), District Councils (DC), Regional Councils (RegC) and Aboriginal Councils (AC)
- Western Australia: Cities (C), Towns (T) and Shires (S)
- Tasmania: Cities (C) and Municipalities (M)
- Northern Territory: Cities (C), Towns (T), Community Government Councils (CGC) and Shires (S).

England and Wales

In England and Wales, the status of a city is reserved for places that have a Royal Charter entitling them to the name, traditionally associated with the possession of a cathedral. Some large municipalities are legally boroughs but not cities, whereas some cities are quite small — St. David's for instance. It is often thought that towns with bishops' seats rank automatically as cities: however, Chelmsford remains a town despite being the seat of the Diocese of Chelmsford. St. Asaph, which is the seat of the Diocese of St. Asaph, is another such town. Within Greater London, there are two cities, each with its own cathedral - the City of London (St. Paul's Cathedral; Anglican) and the City of Westminster (Westminster Cathedral; also Anglican). Historically, a town was generally distinguished from a village by having a regular market or fair. Not all towns were boroughs. There are some English villages (e.g. Kidlington, Oxfordshire) larger than some small towns (e.g. Middleham, North Yorkshire). The word town can also be used as a general term for urban areas, including cities. In this usage, a city is a type of town — a large one, with a certain status. For example, London is a city, but is sometimes referred to as "London town" (the "City of London" is the nucleus informally known as the "Square Mile"). Also, going from the suburbs to central London is to "go into town".

Germany

Germans do not differentiate between city and town. The German word for both is "Stadt" as it is in many other languages that do not make any difference between the Anglo-Saxon concepts. A town with more than 100,000 inhabitants is called a Großstadt, which is the most adequate equivalence for city.

The United States

City of London In the United States of America, the meaning of the term town varies from state to state. In some states, a town is an incorporated municipality, that is, one with a charter received from the state, similar to a city. Typically, municipalities are classed as cities, towns or boroughs, or villages in decreasing order of size, although not all states have all three levels. Many states do not use the term "town" for incorporated municipalities. In some states, for example Wisconsin, "town" is used in the same way that civil township is used in elsewhere. In other states, such as Michigan, the term "town" has no official meaning and is simply used informally to refer to a populated place, whether incorporated or not. In the six New England states, a town is a municipality, and in these states, in practice a more important unit than the county. In Connecticut and Rhode Island, in fact, counties only exist as map divisions and have no legal functions; in the other four states, counties are primarily judicial districts, with other functions primarily in New Hampshire and Vermont. In all six, towns perform functions that in most states would be county functions. The defining feature of a New England town, as opposed to a city, is that a town meeting and a board of selectmen serve as the main form of government for a town, while cities are run by a mayor and a city council. For example, Brookline, Massachusetts is a town, even though it is fairly urban, because of its form of government. In New York, a town is similarly a subdivision of the county, but with less importance than in New England. Of some importance is the fact that, in New York, a town provides a closer level of governance than its enclosing county, providing almost all municipal services to unincorporated areas, called hamlets and selected services to incorporated areas, called villages. In New York, a town typically contains a number of such hamlets and villages. However, due to the independent nature of Incorporated Villages, they may exist in two towns or even two counties. Everyone in New York State who does not live in an Indian reservation or a city lives in a town and possibly in one of the town's hamlets or villages. (Some other states have similar entities called townships.) In New York, "town" is essentially short for "township." In Virginia, a town is an incorporated municipality similar to a city (though with a smaller required minimum population), but while cities are by Virginia law independent of counties, towns are contained within a county. In California (where the term "village" is not used), "town" is simply another word for "city" (especially a "general law city", as distinct from a "charter city").

Hamlet (place)

A hamlet is (usually — see below) a small settlement, too small or unimportant to be considered a village. The name comes from the diminutive of a Germanic word for an enclosed piece of land or pasture.

United Kingdom

In the UK, a hamlet is traditionally defined ecclesiastically. It is a village that may or may not have its own church, but which does not form a parish in its own right. In modern usage it generally refers to a secondary settlement in a civil parish, after the main settlement (if any). The status has no formal definition. [http://www.visionofbritain.org.uk/types/status_page.jsp?unit_status=Hmlt]

United States

New York

In the U.S. state of New York, hamlets are unincorporated areas within towns. Unlike villages, hamlets are not legal entities and have no local government or official boundaries. Municipal government services are provided by the town in which the hamlet is located. :See further: Political subdivisions of New York State.

Oregon

:See Hamlet (Oregon)

Canada

In numerous provinces in Canada, there are officially designated municipalities, generally smaller than villages, classified as hamlets. There are some exceptions, such as Sherwood Park, Alberta, which has a population of more than 50,000 – well above that needed for city status — but which has retained hamlet status. Fort McMurray, Alberta used to be a city, but has now been amalgamated into the Regional Municipality of Wood Buffalo, thus making it a hamlet. Hamlets are always unincorporated, except in Canada's northern territories, where they are incorporated municipalities.

De jure

De jure (in Classical Latin de iure) is an expression that means "based on law", as contrasted with de facto, which means "in fact". The terms de jure and de facto are used like "in principle" and "in practice" when one is describing political situations. They are also often used when discussing racial segregation. A practice may exist de facto, where the people obey a contract as though there were a law. A process known as "desuetude" may allow de facto practices to replace obsolete laws. On the other hand, practices may exist de jure and not be obeyed or observed by the people. The Latin de jure should not be confused with the French du jour, which translates to "of the day", as, for example, in soupe du jour. De jure and de facto standards can differ; for example, the U.S. has no de jure language, whereas the de facto language is English. Similarly, the U.S. de jure standard for measurement of road distances is the kilometre (as the U.S. is party to the Convention du Mètre), but the de facto standard is the mile.

- In archaeology, a core is a distinctive artifact that results from the practice of lithic reduction. In this sense, a core is the scarred nucleus resulting from the detachment of one or more lithic flakes from a lump of source material or tool stone, usually by using a hard hammer percussor such as a hammerstone.
- In astrophysics, the core of a star is its center where nuclear fusion takes place. In astrophysics and geology, a planetary core is the composite material at the centre of a planet.
- In various branches of Earth science a core is a Core sample.
- In biology, the core of a fruit contains its seeds.
- In computing:
  - (Execution) core is the computation engine of a processor. It consists of integer and floating point processing units. See Multicore.
  - Core memory or storage is memory made of magnetic toruses.
  - Core nowadays usually means primary storage regardless of hardware technology (typically semiconductor random access memory).
  - A core dump is a record of the contents of primary storage.
  - In Unix and Unix-like operating systems, core is a file that contains a memory dump -- known as a core dump -- of a computer program that has crashed for some reason. It is used for debugging purposes.
  - Hardware description language (HDL) modules, when distributed, are called "cores" (see open hardware).
- In construction, when the force in an element is within a certain center section, the core, the element will only be under compression.
- In economics, the core is a feasible allocation in an economy that cannot be improved upon by any coalition of consumers.
- In mathematics, the core of a group is an object appearing in group theory.
- In a nuclear reactor, the core is the portion containing the fuel components.
- In planetary science, the core of a planet contains its innermost layer(s). Due to planetary differentiation, such layers tend to be denser than outer layers.
- In fiber optics, the core of an optical fiber is the central region about the longitudinal axis, which supports guiding of the optical signal.
- In electronics, a piece of ferromagnetic material, usually toroidal in shape, used as a component in a computer core memory device or a transformer.
- The material at the center of an electromechanical relay or solenoid, about which the coil is wound.
- In injection moulding, the core is the solid part of the mould that helps shape the plastic material injected.

Suburb

:"Suburban" redirects here. For the sport utility vehicle (SUV), see Chevrolet Suburban. Chevrolet Suburban Suburbs are inhabited districts located either on the outer rim of a city or outside the official limits of a city (the term varies from country to country), or the outer elements of a conurbation. The presence of certain elements (whose definition varies amongst urbanists, but usually refers to some basic services and to the territorial continuity) identifies a suburb as a peripheral populated area with a certain autonomy, where the density of habitation is usually lower than in an inner city area, though state or municipal house building will often cause departures from that organic gradation. Suburbs have typically grown in areas with an abundance of flat land near a large urban zone, usually with minimal traditions of citizens clustering together for defence behind fortified city walls, and with transport systems which allow commuting into more densely populated areas with higher levels of commerce.

Semantics

The word "suburb" is derived from the Old French "sub(b)urbe" and ultimately from the Latin "suburbium," formed from "sub," meaning "under," and "urbs," meaning "city." (Note that urbs was pronounced oorps.) The first recorded usage according to the Oxford English Dictionary comes from Wyclife, in 1380, where the form "subarbis" is used. In American English, the word "suburb" usually refers to a separate municipality or an unincorporated area outside of a central city. This definition is evident, for example, in the title of David Rusk's book Cities Without Suburbs, which promotes metropolitan government. Colloquial usage sometimes shortens the term to "'burb" (with or without the apostrophe), and "The Burbs" first appeared as a term for the suburbs of Chicagoland. In Britain, Australia and New Zealand, "suburbs" are merely residential neighbourhoods outside of the city centre. For example, Clifton is considered a suburb of Bristol, England. Many characteristics of suburbia were found in Australia as early as the 19th century. With huge expanses of land needing to be populated, lack of need for defense as well as the popularity of railroads (which grew at at a swift rate) contributed to sprawling urbanism somewhat resembling suburbia. However, the key commercial element - commuting to work - was not really there, although it would appear during the 20th century. The term suburb as used in Australia reflects this, and thus has a slightly ambiguous meaning to non-Australians. Suburbs there are official postal and addressing subdivisions of a city. Inner suburbs are subdivisions within the denser urban areas of the cities, and correspond to what would be called neigbourhoods in North American cities. For instance, Ultimo, postcode 2007, is an inner suburb of Sydney, even though it lies within the boundaries of the City of Sydney. Locals will refer to Ultimo as a suburb even though it is a densely urban neighbourhood. Outer suburbs are the postal divisions found in the outer rings of the metropolitan areas, and usually lie within the boundaries of a separate municipality, such as the City of Parramatta.

History

Many sociologists see suburbs as a post-urban area which develops in response to worsening conditions within a city with a communication and transport system which allows citizens to live outside the city while doing business inside. The suburbs and more distinct settlements around a town or city may look towards the urban area for goods, services and employment opportunities. That wider area may be called the hinterland of the town or a "city region". In the era before motorised travel, the radius of the hinterland roughly coincided with the distance that livestock could be herded to and from a market during daylight hours. In lowland areas, without severe geographic barriers to movement, a spacing of towns between 15 and 20 miles is therefore quite common. Suburbs with a healthier environment are often found upwind of those parts of a town or city where heavy industry was first established. Naturally, the suburbs suffering air pollution tended to be cheaper and hence tend to be occupied by those with lower incomes. The growth of suburbs was initially facilitated by the development of zoning laws and more effective and accessible means of transport. In the older cities of the northeast U.S., suburbs originally developed along train or trolley lines that could shuttle workers into and out of city centers where the jobs were located. This practice gave rise to the term bedroom community or dormitory, meaning that most daytime business activity took place in the city, with the working population leaving the city at night for the purpose of going home to sleep. The growth in the use of trains, and later automobiles and highways, increased the ease with which workers could have a job in the city while commuting in from the suburbs. In the United Kingdom, railways stimulated the first mass exodus to the suburbs, which were described as "Metroland" around London, and were mostly characterised by semi-detached houses. As car ownership rose and wider roads were built, the commuting trend accelerated as in North America. This trend towards living away from towns and cities has been termed the urban exodus. Zoning laws also contributed to the location of residential areas outside of the city center by creating wide areas or "zones" where only residential buildings were permitted. These suburban residences are built on larger lots of land than in the urban city. For example, the lot size for a residence in Chicago, Illinois is usually 125 feet deep, while the width can vary from 14 feet wide for a row house to 45 feet wide for a large standalone house. In the suburbs, where standalone houses are the rule, lots may be 85 feet wide by 115 feet deep, as in the Chicago suburb of Naperville, Illinois. Manufacturing and commercial buildings were segregated in other areas of the city. Increasingly, due to the congestion and pollution experienced in many city centers (accentuated by the commuters' vehicles), more people moved out to the suburbs. Moving along with the population, many companies also located their offices and other facilities in the outer areas of the cities. This has resulted in increased density in older suburbs and, often, the growth of lower density suburbs even further from city centers. An alternative strategy is the deliberate design of "new towns" and the protection of green belts around cities. Some social reformers attempted to combine the best of both concepts in the Garden City movement. While suburbs had originated far earlier, the suburban population in North America exploded after World War II. Returning veterans wishing to start a settled life moved en masse to the suburbs. Between 1950 and 1956 the resident population of all US suburbs increased by 46%. During the same period of time, African-Americans were rapidly moving north for better jobs and educational opportunities than they could get in the segregated South, and their arrival in Northern cities en masse further stimulated white suburban migration. Many people equate suburbs with early planned cities such as Levittown, New York and Rohnert Park, California. Rohnert Park, a suburb of Santa Rosa, California and San Francisco, California was originally marketed in the late 50's as "A Country Club for the middle class." In the US, 1970 was the first year that more people lived in suburbs than elsewhere. (1) The development of the skyscraper and the sharp inflation of downtown real estate prices also led to downtowns being more fully dedicated to businesses, thus pushing residents outside the city centre. By 1980 this was often perceived as undesirable, extending travel times and adding to people's sense of isolation and fear in central areas outside trading hours. 1

Suburbs today

In North America, suburbs traditionally were residential areas with single-family homes located near shopping areas and schools, with good access to trains, freeways or other transport systems. Now, partly due to increased populations in many greater metropolitan areas, suburbs can be densely populated and contain apartment buildings and townhouses, as well as office complexes, light manufacturing facilities, and shopping centers or malls. It is not unusual for suburbs to house several hundred thousand people. In fact, many American and Canadian suburbs are now larger than other urban population centers. For example, Mesa, Arizona (a suburb of Phoenix, Arizona), is larger than St. Louis, Missouri; Pittsburgh, Pennsylvania; and Salt Lake City, Utah, and grew at a much faster rate than even Phoenix between 1990 and 2000. Another example is Mississauga, Ontario (a suburb of Toronto, Ontario). Mississauga is the largest suburban municipality in all of North America, with a population of 636,801 and a population density of 2125.1/km². Mississauga is larger than the U.S. cities of Milwaukee, Wisconsin; Boston, Massachusetts; Washington DC; Nashville, Tennessee; Seattle, Washington; Portland, Oregon; New Orleans, Louisiana; Las Vegas, Nevada; Cleveland, Ohio; Atlanta, Georgia; Sacramento, California; Minneapolis, Minnesota; Miami, Florida etc. Mississauga also has a higher population than the city of Vancouver, British Columbia. The five largest suburbs in North America, in order, are Mississauga, Ontario; Mesa, Arizona; Virginia Beach, Virginia; Surrey, British Columbia; and Laval, Quebec. In one metropolitan area, the Hampton Roads area of Virginia, the largest city is actually a suburb, namely Virginia Beach. Although the United States Census Bureau officially calls the area the Virginia Beach-Norfolk-Newport News Metropolitan Statistical Area, in keeping with its normal practice of putting the most populous city in a metropolitan area in the lead position of its name, the naming does not reflect the actual character of the area. Despite recent efforts by city leaders in Virginia Beach to create a more urban environment, the urban core of the area lies in Norfolk, which will soon become the third-largest city in the region. Chesapeake, which is not part of the area name but has already surpassed Newport News in population, is growing at a rate that will probably see it also surpass Norfolk in population well before the 2010 Census. A socio-political movement called "New Urbanism" or "Smart Growth" is currently in vogue in the U.S.A., Canada and northern Europe, in response to the perceived threat of "urban sprawl". This movement among city planners, builders, and architects holds that denser, more city-like communities with less rigid zoning laws and mixed-use buildings are desirable. Such communities ease traffic, since people do not need to commute as far, and may foster a better sense of community among residents. Some of these communities seek to reduce car-dependency (and thus the use of personal automobiles) wherever possible. This movement has resulted in both the construction of new developments that embody these principles, and renovation of areas in existing city centers for new residential and commercial activities. In the UK, the government is (2003) seeking to impose minimum densities on newly approved housing schemes in parts of southeast England. Whether any society succeeds in reducing the average distance travelled by each citizen by means of such planning strategies remains to be seen. The new catchphrase is 'building sustainable communities' rather than housing estates. In England this is displacing the now discredited notion of 'urban villages', but the credibility of both ideas is challenged by the increasing involvement of commercial interests in developing new hospitals, secondary schools and public transport services. Commercial concerns tend to retard the opening of services until a large number of residents have occupied the new neighbourhood. In many parts of the globe, however, suburbs are economically poor areas, inhabited by people sometimes in real misery, that keep at the limit of the city borders for economic or social reasons like the impossibility of affording the (usually higher) costs of life in the town. An example in the developed world would be the banlieues of France, which are comparable to the inner cities of the UK and US. In the Third World, such slum areas are often irregularly built or managed, with individualistic, unregulated building and other forms of social or legal disorder. It has been said that this would be sometimes a case of spontaneous or psychological apartheid. In some cases inhabitants just live off the waste materials produced by the city (like, increasingly, around new African towns) and usually in such situations suburbs and houses are roughly built, often not even in the traditional building materials, as seen for example in the bidonvilles. Often nomads settle their camps in suburbs. The occupiers of more industrialised or longer-lasting homes may refer to such suburbs as "shanty towns". The favelas of Rio de Janeiro may also be considered an example of this type of suburb. In the illustrative case of Rome, Italy, in the 1920s and 1930s, suburbs were intentionally created ex novo in order to give lower classes a destination, in consideration of the actual and foreseen massive arrival of poor people from other areas of the country. Many critics have seen in this development pattern (that was circularly distributed in every direction) also a quick solution to a problem of public order (keeping the unwelcome poorest classes - together with criminals, in this way better controlled - comfortably remote from the elegant "official" town). On the other hand, the expected huge expansion of the town soon effectively covered the distance from the central town, and now those suburbs are completely engulfed by the main territory of the town, and other newer suburbs were created at a further distance from them.

Suburbs in pop culture

Suburbs on TV

Hot Choice Channel's Original Movie, Suburbian Sex Addict, 2004. Neighbours has been on television in Australia since 1985 and the United Kingdom from the following year. It is set in Ramsay Street in suburban Erinsborough. Knots Landing was a long-running show depicting suburban life. It was set in the fictional town of Knots Landing, California, and followed the lives of several families who lived on the suburban cul-de-sac Seaview Circle. The Australian show Kath & Kim pillories the nouveau white trash of subdivisions with exaggerated provincial accents and below-average intelligence. Suburban life through the eyes of stay-at-home wives and mothers is portrayed in the ABC television series Desperate Housewives. Many U.S. sit-coms are set in the suburbs, including the animated Family Guy and The Simpsons.

Rural

]] Rural areas are sparsely settled places away from the influence of large cities and towns. Such areas are distinct from more intensively settled urban and suburban areas, and also from unsettled lands such as outback or wilderness. People live in villages, on farms and in other isolated houses. Rural areas can have an agricultural character, though many rural areas are characterized by an economy based on logging, mining, oil and gas exploration, or tourism. Lifestyles in rural areas are different than those in urban areas, mainly because limited services are available. Governmental services like law enforcement, schools, fire departments, and libraries may be distant, limited in scope, or unavailable. Utilities like water, sewer, street lighting, and garbage collection may not be present. Public transport is absent or very limited, people use their own vehicles, walk, bicycle, or ride an animal.

City centre

:For other meanings of the term downtown, see downtown (disambiguation). :"City center" redirects here. For the performing arts venue, see New York City Center. New York City Center, United States, an example of an urban downtown district]] Central business district (CBD) and downtown are terms referring to a commercial heart of a city. Downtown is the usual term in North America. In the United Kingdom, Hong Kong, Ireland, Australia, South Africa and New Zealand the term "central business district" is used by geographers and sometimes by others, but the term city centre is much more common in colloquial usage. In the United Kingdom, Ireland, Australia, South Africa and New Zealand, the term is often just shortened to the single word "city" in general conversation among residents of a city, giving rise to the phrase "going to the city". One exception is in London where "the City" specifically refers to the City of London financial district rather than to any other part of central London. Some cities have a mixed use district known as uptown near the downtown area (in Minneapolis, for example, Uptown is a district nearly adjacent to downtown, centered around the Uptown Theater on the intersection of Lagoon St. and Hennepin Ave.) On the other hand, in some cities, like Charlotte, North Carolina, uptown is simply the historic name for the business center. The CBD or downtown is the central district of a city, usually typified by a concentration of retail and commercial buildings. Although applicable to any city, both terms usually refer to larger cities. The term city centre (or center city) is similar to CBD or downtown in that both serve the same purpose for the city, and both are seen by a higher-than-usual urban density as well as the often having the tallest buildings in a city. City centre differs from downtown in that downtown can be geographically located anywhere in a city, while city centre is located near the geographic heart of the city. Examples of a city centre can be found in Philadelphia, Boston, Pittsburgh, Seattle, Vancouver, Toronto, London, Sydney, and other cities. London effectively has two city centres rolled into one, namely the Roman City of London, and the medieval City of Westminster.

List of typical CBD characteristics

A CBD is likely to have many of the following characteristics:
- It has a distinct land use pattern that can be delimited from the rest of the settlement.
- It is the geographical centre of the settlement.
- It contains the settlement's main public buildings.
- It contains the major retail outlets (though this is becoming less often the case, especially in the United States).
- Similar activities within it are concentrated in certain areas (functional zoning).
- It features vertical zoning.
- It has the greatest concentration and number of pedestrians and traffic in general.
- It is a focal point for transport.
- It contains the greatest proportion of the settlement's offices.
- It has the tallest buildings in the region to maximize land use.
- It has the highest land values of the region.
- It attracts people from outside its sphere of influence to work and spend money inside.
- It is advancing into new areas (assimilation) and/or losing old commercial functions (discard).

Residential

A residential area is a type of land use where the predominant use is residential. In areas that are zoned residential, buildings may include single family housing, multiple family housing, (apartments, duplexes (or similar configurations), condominiums) or mobile homes. Zoning for residential use may permit some services or work opportunities or may totally exclude business and industry. It may permit high density land use or only permit low density uses. In certain situations residential areas may consist of quite large tracts of land which have no services whatever requiring a trip to town in order to fulfill basic needs. Because of the large distances involved most of these numerous trips involve using a motor vehicle. In the case of a land development the pattern of development is set forth in the restrictive covenants contained in the deeds to the properties in the development. This creates a situation which is not easily changed as the agreement of all property owners (many of whom may not live in the area) must be obtained to effect a change.

Geography

)]] Geography is the study of the locational and spatial variation of both natural and human phenomena on Earth. The word derives from the Greek words Ge (γη) or Gaea (γεια), both meaning "Earth", and graphein (γραφειν) meaning "to describe" and "to write". Modern geography is a diverse discipline that draws influence from almost every other arena of knowledge. Geographers engage with other disciplines according to their particular research interests and, while subjects such as biology and economics have a powerful influence, there are geographers who use concepts taken from subjects such as sociology, psychology and sports science, among many others. Within the discipline there have been many long-running tensions among those seeking to define geography - whether as a 'science' or as a 'humanity', as a 'systematic' subject or 'regional' specialism and so forth - which at various times have come close to destroying geography as an academic discipline. Whilst profound differences do exist among geographers, the dual concepts of space and place provide a commonality of interest, which gives the subject a unique identity.

Structure of geography

William Hughes - who taught the geography of the Holy Lands to divinity students at King's College London - defined geography in an address in 1863: :"Mere place names are not geography. To know by heart a whole gazeteer full of them would not, in itself, constitute anyone a geographer. Geography has higher aims than this: it seeks to classify phenomena (alike of the natural and of the political world insofar as it treats of the latter) to compare, to generalise, to ascend from effects to causes and in doing so to trace out the great laws of nature and to mark their influence upon man. In a word, geography is a science, a thing not of mere names, but of argument and reason, of cause and effect." This was a specific rejection of geography as a merely descriptive discipline and also defined it as inclusive of both the physical world and the human. Within the discipline, however, there are many areas of specialism. Modern geographers tend to specialise in one of the broad branches (or sub-branches). However, most introductory geography syllabuses seek to ensure that geographers have at least working knowledge of the main focus of each branch of the subject.

Physical geography

Physical geography (or physiogeography) focuses on geography as an Earth science. It aims to understand the physical layout of the Earth, its weather and global flora and fauna patterns. Many areas of physical geography make use of geology, particularly in the study of weathering and sediment movement. Physical Geography can be divided into the following broad categories:
- Geomorphology
- Hydrology
- Glaciology
- Biogeography
- Climatology
- Pedology (soil study)
- Coastal/Marine studies
- Geodesy
- Palaeogeography
- Environmental Geography and management
- Landscape ecology Exact lines between these different areas are often difficult to draw. Sometimes Oceanography is included as a branch within physical geography, but is now considered a separate subject in its own right. Related topics: Atmosphere - Archipelago - Continent - Desert - Island - Landform - Ocean - Sea - River - Lake - Ecology - Soil - Timeline of geography, paleontology - Geostatistics - Environmental science - Oceanography - Environmental studies

Human geography

Human geography is a branch of geography that focuses on the study of patterns and processes that shape human interaction with various environments. It encompasses human, political, cultural, social, and economic aspects. While the major focus of human geography is not the physical landscape of the Earth (see Physical geography) it is hardly possible to discuss human geography without referring to the physical landscape on which human activities are being played out, and environmental geography is emerging as a link between the two. Human geography can be divided into broad categories, such as:
- Economic geography
- Development geography
- Population geography or Demography
-
- Urban geography
- Social geography
- Behavioral geography
- Cultural geography
- Political geography, including Geopolitics
-
- Historical geography
- Regional science
- Strategic geography
- Military geography
- Feminist geography
- Distinction between these fields of study have become increasingly blurred over time and the above list should not be considered definitive.

Socio-environmental geography

During the time of environmental determinism, geography was defined not as the study of spatial relationships, but
