The U.S. Census Bureau has released updated population estimates and projections extending to the year 2100 for 21 countries and areas, as part of its International Database (IDB). This update also covers 13,671 subnational regions worldwide, which are comparable to U.S. states, counties, and townships. The latest data release includes enhanced mapping features.
Countries with revised estimates and projections include Australia, Bangladesh, Barbados, Botswana, Burundi, Cameroon, El Salvador, Eswatini, Guatemala, Iran, Jamaica, Lesotho, Madagascar, Malawi, Nigeria, Philippines, Rwanda, Togo, Tunisia, the United States, and Zambia.
The new information is based on recent censuses, surveys and administrative records. Analyses have been updated accordingly to reflect these sources.
According to the Census Bureau: “The IDB consists of estimates and projections of demographic indicators, including population size and growth (by sex and single year of age up to 100-plus) and components of change (mortality, fertility and net international migration) for more than 220 countries and areas. The Census Bureau periodically updates the IDB as new data become available.”
