The Population Projections Program produces projections of the United States resident population by age, sex, race, Hispanic origin and nativity. These projections are based on assumptions about future births, deaths, and international migration. Although alternative series are produced, the preferred (or middle) series is most commonly used. The Census Bureau releases new national population projections periodically.
