Overview

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.

The IDB provides estimates and projections for 228 countries and areas which have populations of 5,000 or more and as recognized by the U.S. Department of State. Population size (by single year of age and sex) and components of change (fertility, mortality, and migration) are provided from an initial or base year through 2050, for each calendar year.  This level of detail provides an important foundation for tracking the demographic impacts of HIV/AIDS and related conditions, as well as events of concern that are affecting populations around the globe.

Documentation

The IDB is designed to provide customers with open access to quality data that can inform research, program planning, and policy making.   Estimates and projections provided in the IDB are developed through the evaluation and adjustment of data from reliable sources and with the cohort-component projection methodology. 

Documentation on how the cohort-component methodology is applied in generating IDB data is available in .pdf form that can be viewed, printed, or saved.
