The U.S. Census Bureau has released updated international population estimates and projections extending to the year 2100 for 21 countries and areas. The data, now available in the International Database (IDB), include new analyses that refine population estimates for countries such as Australia, Bangladesh, Nigeria, the United States, and others.
This update also covers demographic information for 13,671 subnational regions comparable to U.S. states, counties, and townships worldwide. The enhancements feature improved mapping capabilities to support users in exploring global demographic patterns.
The latest release incorporates recent data from censuses, surveys, and administrative records to provide more accurate analyses of population trends. The IDB includes demographic indicators like population size by sex and single year of age up to 100-plus years old. It also details components of change such as mortality rates, fertility rates, and net international migration across more than 220 countries and areas.
The Census Bureau regularly updates the IDB as new data are collected and analyzed. Estimates and projections from this database can be accessed through the International Database Overview webpage at https://www.census.gov/data-tools/demo/idb/region.php?T=1&RT=0.
