The U.S. Census Bureau has published updated population estimates and projections extending to the year 2100 for 21 countries and regions through its International Database (IDB). This update includes refined demographic data for countries such as Australia, Bangladesh, Nigeria, the United States, and others.
According to the announcement, new information was used to improve estimates for both national populations and 13,671 subnational areas globally. These subnational areas are comparable to U.S. states, counties, and townships. The update also brings enhanced mapping features.
The revised data draws from recent censuses, surveys, administrative records, and updated analyses based on those sources.
The IDB offers demographic indicators such as population size by sex and single years of age up to 100-plus years old. It also covers components of change including mortality rates, fertility rates, and net international migration for over 220 countries and areas. The Census Bureau regularly updates this database when new information is available.
