Population Reference Bureau




The U.S. data in PRB's DataFinder are from the U.S. Census Bureau's decennial census, American Community Survey, and population estimates.

The international data in PRB's DataFinder are from several Population Reference Bureau data sheets. Additional international indicators were compiled by PRB staff, primarily using national surveys.

Sources for each indicator appear as footnotes for that indicator. More detailed sources are available from PRB.
