How does it work?

City and urban area population

Source: http://citymayors.com/statistics/urban_2006_1.html

From CityMayors.com:

The tables provide population figures for cities and their surrounding urban areas. Most such agglomerations are economically, socially and culturally dominated by one city at their centre. Occasionally however, several cities of similar status and their suburbs make up an urban area. The 2006 population figures are based on censuses carried out between 2000 and 2005 and adjusted to take account of average annual population changes.
