The population projections for 2000 to 2050 associated with this release were produced by the Population Division as an interim product to meet the immediate needs of our user community for national projections that incorporate the results of Census 2000. While not encompassing the full matrix of race and Hispanic-origin categories, the race groups for which these interim population projections are available include: (1) White alone, (2) Black alone, (3) Asian alone, and (4) All other races alone and Two or More Races. Other groups include: (1) Hispanic origin, (2) Hispanic White alone, (3) non-Hispanic origin, and (4) non-Hispanic White alone.
The beginning population for these projections is the resident population of the United States classified by age, sex, race, and Hispanic origin consistent with the Census 2000 modified race data. The assumptions about the components of population change (fertility, mortality, and international migration) are based on those developed for the last full set of projections released in January 2000.
