For 2011 census data there are 5,493 built-up areas, of which 501 are divided into Built-up area sub-divisions (BUASD) for which data is also available. Each built-up area is named algorithmically, using Ordnance Survey place-name data. The ONS has produced census results from urban areas since 1951, since 1981 based upon

By 2014, it was 3.9 billion or about 53 percent of the world's 7.3 billion people that lived in urban areas. The change was driven by a combination of increased total population and increased percent of population living in urban areas. In 2009, the number of people living in urban areas (3.42 billion) surpassed

There were 2,646 urban areas identified by the Census Bureau for 2020. 511 of these had a population of 50,000 or more. For the 2000 and 2010 censuses, the Census Bureau differentiated between two kinds of urban areas: urbanized areas and urban clusters. The term urbanized area denoted an urban area of 50,000 or more people. Urban areas under 50,000 people were called urban clusters . Urbanized areas were first delineated in

Accordingly, the new definition set out three distinct types of population centres: small (population 1,000 to 29,999), medium (population 30,000 to 99,999) and large (population 100,000 or greater). Despite the change in terminology, however, the demographic definition of

Any areas [separated by] less than 200 metres [of non-urban space] are linked to become a single built-up area. Argentina and Japan are countries where the urbanization rate is over 90% while Australia, Brazil, Canada, Chile, Mexico and

Statistics New Zealand defines urban areas in New Zealand, which are independent of any administrative subdivisions and have no legal basis. There are four classes of urban area: major urban areas (population 100,000+), large urban areas (population 30,000–99,999), medium urban areas (population 10,000–29,999) and small urban areas (population 1,000–9,999). As of 2021, there are 7 major urban areas, 13 large urban areas, 22 medium urban areas and 136 small urban areas. Urban areas are reclassified after each New Zealand census , so population changes between censuses does not change an urban area's classification. According to Statistics Canada , an urban area in Canada

Part VI of the RTRA 1984 deals specifically with speed limits, with Sections 81–84 dealing with different speed limits and the speed-limit order-making process. In Northern Ireland, the Highway Code of Northern Ireland has only three references to the "built-up area" and does not define it. In Northern Ireland,
1155-565: The U.S. Department of Agriculture 's natural resources inventory , urban areas are officially known as developed areas or urban and built-up areas. Such areas include cities, ethnic villages, other built-up areas of more than 10 ac (4 ha), industrial sites, railroad yards, cemeteries, airports, golf courses, shooting ranges, institutional and public administration sites, and similar areas. The 1997 national resources inventory placed over 98,000,000 ac (40,000,000 ha) in this category, an increase of 25,000,000 ac (10,000,000 ha) since 1982. Argentina

The second measure, rate of urbanization, describes the projected average rate of change of the size of the urban population over
1540-565: The United States in the 1950 census, while urban clusters were added in the 2000 census. The distinction between urbanized areas and urban clusters was removed for the 2020 census. Urban areas consist of a densely-settled urban core, plus surrounding developed areas that meet certain density criteria. Since urban areas are composed of census blocks and not cities, counties, or county-equivalents, urban area boundaries may consist of partial areas of these political units. Urban areas are distinguished from rural areas : any area not part of an urban area

The Population Division of the United Nations Department of Economic and Social Affairs at that time predicted the urban population would occupy 68% of the world population by 2050, with 90% of that growth coming from Africa and Asia. Urban areas are created and further developed by the process of urbanization. They are measured for various purposes, including analyzing population density and urban sprawl . Urban areas are also mostly found in

European countries define urbanized areas on the basis of urban-type land use , not allowing any gaps of typically more than 200 metres (220 yd), and use satellite imagery instead of census blocks to determine the boundaries of the urban area. In less-developed countries , in addition to land use and density requirements, a requirement that

It defines the road as a road within built-up area if some system of street lighting exists at less than 200 yards (183 meters) from that road, unless decided other way by the local authority and written on traffic signs. The Road Traffic Regulation Act 1984 is the basis of

This states that speed-limit repeater signs cannot be placed along a road on which there is carriageway lighting not more than 183 metres apart and which is subject to a 30 mph speed limit.

Other relevant legislation includes

The concept of an "urban area" as used in economic statistics should not be confused with the concept of the "urban area" used in road safety statistics.
