"The International Data Base (IDB) was developed by the U.S. Census Bureau to provide access to accurate and timely demographic measures for populations around the world. The database includes a comprehensive set of indicators, as produced by the U.S. Census Bureau since the 1960s. Through sponsorship from various U.S. Government agencies, the IDB is updated on a regular basis to provide information needed for research, program planning, and policy-making decisions, in the U.S. and globally.
Data included in the IDB consist of indicators developed from censuses, surveys, administrative records, and special measures of HIV/AIDS-related mortality. Through evaluation and adjustment of data from these sources, measures of population, mortality, fertility, and net migration are estimated for current and past years and then used as the basis for projections to 2050..."International statistics
