The International Data Base (IDB) offers a variety of demographic indicators for countries and areas of the world with a population of 5,000 or more. World and Region demographic indicators in the IDB, including population totals, exclude the populations of countries and areas with fewer than 5,000 people. The IDB has provided access to demographic data for over 25 years to governments, academics, other organizations, and the public. It is funded by the Census Bureau's International Programs.
The IDB provides many types of demographic data, including:
· Estimates and projections of:
The following ZIP file contains the complete data set which has currently been released and is used by the International Data Base tool.
IDB_DataSet.zip (11 MB).
The demographic estimates and projections found in the International Data Base are the result of over 30 years of analysis of census, survey, vital statistics, and other data by Census Bureau demographers. The IDB differs from some other online resources in several ways. First, the estimates and projections of vital rates, vital events, and midyear population presented are based on careful evaluation of census and survey results and, in part because of this evaluation process and associated estimation processes, represent a set of consistent estimates and projections of population, fertility, mortality, and international migration. The IDB is not simply a compilation of estimates taken from other sources. Second, estimates from original sources are accurately dated, and derived estimates of fertility and mortality available from the IDB reflect that dating. Third, the projections are generated using the Census Bureau's Rural/Urban Projection (RUP) program, which projects population, by single years of age, for each calendar year beyond a base year. This means IDB fertility and mortality estimates pertain to specific years rather than being average values for 5-year periods. It also means that the impact of natural disasters, civil conflicts, and changes in the health climate in a country can be reflected in year-specific estimates of fertility, mortality, and migration found in the IDB. Finally, the data are accessible in multiple ways to meet different user needs.
The following reports cover fertility, mortality, and migration:
The following reports give data for the population age structure (provides population for both sexes, male, and female, percent of these age groups for both sexes, male, and female, and sex ratio):
Population Pyramids
The report “Population Pyramid Graph” - provides population pyramid by five year age groups and sex. If only one country and more than one year is selected you can get animation by selecting 
(play button).
The IDB's estimates and projections are prepared by Census Bureau demographers, who review a wide range of data, including censuses, surveys, and vital statistics provided by National Statistics Offices, and data on international migration and refugee movements. We also consider other information, such as public health efforts, socio-political circumstances, and historical events such as natural disasters and conflict.
For additional information, please see our Population Estimates and Projections Methodology page.
Students and researchers, international organizations and governments, planners and businesses, and the public use the data to make informed decisions. The IDB is often cited in journal articles, reports, and other studies and is routinely used as a teaching resource. The IDB is a very popular demographic resource, receiving hundreds of thousands of data queries each month.

Below is a brief summary of revisions for countries experiencing more than a 500,000 change from the previously estimated 2016 population.
The estimated population of Bangladesh in 2016 is 156.2 million, which is about 15.5 million (9.0 percent) less than our previous estimate. This marked decrease is due primarily to a reduction in the base population and, to a lesser extent, lower levels of fertility.
The estimated population of Egypt in 2016 is 94.7 million, which is about 4.6 million (5.1 percent) higher than our previous estimate. This increase is due to both a modest increase in the base population and higher fertility in recent years.
The estimated population of Eritrea in 2016 is 5.9 million, which is about 805 thousand (12.1 percent) less than our previous estimate. The smaller population is due to increased out-migration.
The estimated population of Nepal in 2016 is 29.0 million, 3.1 million (9.6 percent) lower than our previous estimate. The smaller population is due primarily to increased outmigration and to a lesser extent due to decreased fertility estimates in the 1980s and early 1990s.
The estimated population of South Korea in 2016 is 50.9 million, about 1.7 million (3.5 percent) higher than our previous estimate. The larger population is due to increased in-migration in the past 10 years.
The estimated population of Venezuela in 2016 is 30.9 million, which is about 1.2 million (4.2 percent) higher than our previous estimate. The larger population is due to decreases in mortality, and to a lesser extent, upward adjustments to fertility.
