1, urban area: the urban area is smaller than the lost area.
2. Scope of urban area: The scope of urban area is relatively large.
Second, the overview of the two is different:
1. Overview of urban areas: Urban areas refer to areas under the jurisdiction of municipal districts, cities without districts, urban districts and residents' committees of cities without districts, and other areas related to actual construction.
2. General situation of urban areas: one meaning refers to the areas within (administrative divisions), and the other meaning refers to the areas with urban characteristics within the urban areas.
Third, the division of the two is different:
1, division of urban areas:
(1) Cities with a permanent population of less than 500,000 in urban areas are small cities, of which cities with a population of more than 200,000 and less than 500,000 are I-type small cities, and cities with a population of less than 200,000 are II-type small cities.
(2) Cities with a permanent population of more than 500,000 and a population of less than 6.5438+00,000 are medium-sized cities.
(3) Cities with a permanent population of 6,543,800+but less than 5 million are big cities, of which 3 million and less than 5 million are I-type cities and 6,543,800+and less than 3 million are II-type cities.
(4) Cities with a permanent population of more than 5 million10,000 are megacities.
(5) Cities with a permanent population of100000 are megacities.
2, the division of urban areas:
When the urban area is taken as the statistical unit of the city, it is impossible to compare because of the great differences in urban conditions in different countries. In the west, the legal boundaries of cities tend to be stable, and in slightly larger cities, the built-up areas are generally larger than the urban areas. In China, the urban area of almost all cities is larger than the urban built-up area.
In the concepts of urban administrative division and urban statistics in China, the urban areas of municipalities directly under the central government and regional cities refer to urban administrative areas other than counties.
For example, the urban area of Beijing includes two capital functional core areas, namely Dongcheng District and Xicheng District, which are located in the center of the city, and four urban functional expansion areas, namely Haidian District, Chaoyang District, Fengtai District and Shijingshan District, as well as Mentougou District, Fangshan District, Daxing District, Shunyi District, Changping District and Tongzhou District, which are located in the outer suburbs, and Pinggu District and Huairou District, which are far from the center of the city, but not including the two counties under the jurisdiction of Beijing (Miyun County and Yanqing County)
But for a county-level city, the urban area is all its jurisdiction. In most cases, the urban area of a county-level city is equivalent to the whole county before it was changed into an organic city. In addition, there are many mining cities, and their urban areas are often equivalent to the scope of the whole region (including several counties) before they are changed into organizational cities.
The real urban areas are just scattered small places, such as Zibo in China. This kind of statistics does not emphasize the degree of urban characteristics, and often includes a considerable proportion of rural areas and rural population.
Extended data:
Number of administrative units at all levels in urban areas:
1. Provincial Administration: 34 provincial administrative regions (including 4 municipalities, 23 provinces, 5 autonomous regions and 2 special administrative regions).
2. Prefecture-level administrative regions: 334 (excluding Hong Kong, Macao and Taiwan) prefecture-level administrative regions (including: 293 prefecture-level cities, 7 regions, 30 autonomous prefectures and 3 leagues).
3. District-level administrative divisions: 2,853 (excluding Hong Kong, Macao and Taiwan) district-level administrative divisions (including: 872 municipal districts, 368 county-level cities, counties 1442, autonomous counties 1 17, 49 flags, 3 autonomous flags, and special zones/kloc-0).
4. Township-level administrative divisions: 40,497 (excluding Hong Kong, Macao and Taiwan) township-level administrative divisions (including: 2 sub-district offices, 7,566 streets, 20 1 17 towns,1626 townships,1026 townships).
5. Village-level administrative divisions: 662,238 (excluding Hong Kong, Macao and Taiwan) village-level administrative divisions (statistics of administrative divisions below the provincial level exclude Hong Kong, Macao and Taiwan).
