The Population Projections Program produces projections of the resident population for each of the 50 states and the District of Columbia by age, sex, race, and Hispanic origin, consistent with the national population projections. The state projections are based on state-specific data on births, deaths, international migration, and domestic migration. Although several alternative series are produced, the preferred, or middle series--based on the assumption that past and current trends will continue--is most commonly used.
