Subnational Population Database presents estimated population at the first administrative level below the national level. Many of the data come from the country’s national statistical offices. Other data come from the NASA Socioeconomic Data and Applications Center (SEDAC) managed by the Center for International Earth Science Information Network (CIESIN), Earth Institute, Columbia University. It is the World Bank Group’s first subnational population database at a global level and there are data limitations. Series metadata includes methodology and the assumptions made.

Population total is the estimate of de facto mid-year population at first level administrative division (Admin 1 level).

Population Percentage of total is the share of first level administrative division (Admin 1 level) de facto mid-year population to total population.

The population estimates are based on the (1) share of population at first level administrative division (Admin 1 level) from national population censuses and national estimates, and (2) total population estimates from World Development Indicators.

Population percentage of total is based on the share of population at first level administrative division (Admin 1 level) to total population from national population censuses and national estimates.

The process includes the following. The population data from national censuses and national statistical offices are adjusted for mid-year (July 1st) assuming constant growth rate between two data points. For the years to which census or national data are not available, the population figures are interpolated or extrapolated. For interpolation, the constant growth rate between the two data points is assumed. For extrapolation, the same growth rate as the average of earliest (or latest) 3 years is used. Then the share of each admin 1 population to the sum of all admin 1 areas is calculated. If there is only one data point, it is assumed that the share of admin 1 population to the total population remains constant. Admin 1 population estimates (absolute numbers) are then calculated by applying the share of each admin 1 to total population of the World Bank's World Development Indicators' total population estimates.While estimating admin 1 population the latest admin 1 classification for which data is available was used for each country. Data source information by year for each country is included.
