List of metropolitan areas by population

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by 61.119.230.53 (talk) at 17:00, 16 March 2007. The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

Largest city redirects here. For a list of the most populous cities within administrative limits, see List of cities by population. For a list of urban areas, see List of urban areas by population. See also historical urban community sizes for historical data.

This page lists the 100 largest Metropolitan Areas of the world, ranked by population. This is a controversial issue rather difficult to quantify, as unlike national subdivisions, there are no consistently defined borders for such an area. Many of the figures for individual cities are highly controversial, and in some cases numbers which differ by millions are given by different sources. In some countries there are official definitions, but they are not consistent on a global basis, nor even necessarily within countries. In addition, the underlying structure of different metropolitan areas varies: comparing a highly centralised city with an agglomeration of smaller settlements may not be very meaningful. Commuting patterns and other aspects of urban behaviour which underlie the metro area concept differ greatly around the world. Thus, all population figures for specific metro areas should be treated as interpretations rather than hard facts, and rankings and comparisons of metros should be treated with great caution.

Three main definitions

Three main definitions for the extent of a city:

  • A morphological definition based on the urbanized area, which is usually defined as the continuous built-up area with the maximum allowable gap between structures of typically 200 m. This morphological definition is an efficient way of defining the visible city for inhabitants, especially from satellite or aerial view and because it is independent of political boundaries. For statistical convenience, such areas are sometimes adjusted to appropriate administrative limits, sometimes including rural areas within the adjusted boundaries. The urban area definition is what would traditionally be called "the city" with limits that can easily be delineated from the air and is not dependent on how a country is administratively subdivided.
  • A functional definition, which is the traditional concept of a Metropolitan Area. This definition is based on commuting from home to work. Commuter flow thresholds into the core urban area are established by the national census authority to determine which areas are included or not in the metropolitan area. This definition, however, often encompasses large periurban rural areas that are not usually considered as "cities".
  • An administrative definition, typically based on a municipality (city proper) or equivalent entity, or sometimes a group of municipalities under a regional government. While statistical data for administrative divisions are easy to collect, they often do not reflect the true extent of the city.

Definitions used here

Most of the data for this list were compiled from the 2005 urban agglomeration population figures from the United Nations 2005 World Urbanization Prospects Report.[1] These figures include a single urban/employment center and its immediately surrounding suburban areas. Figures with notations are from the indicated sources instead of the UN report.

Unless otherwise specified, figures are based on rough estimates for the year 2005 and rounded to the nearest 1,000. Despite the standing of the organisation behind the figures, the appropriateness and consistency of the boundaries used is controversial and the aforementioned warnings apply.
