Annual estimates of the population of the United States by single years of age to 100, sex, race, and Hispanic origin are presented in this report. Total population figures for the Asian and Pacific Islander population, as well as the American Indian, Eskimo, or Aleut populations also are represented. Estimates for each year from July 1, 1980 to July 1, 1988 are included. Estimates are shown for the total population including Armed Forces overseas, the resident population, and the civilian population. Monthly population estimates are provided for January 1, 1950 to January 1, 1989. Tables of statistical data with related textual commentary comprise the body of the report. The interest of this report to educators can be exemplified in one of the report's highlights: "The population of elementary school age, 5 to 13 year, declined early in the decade, then began to grow again. The 1985 population of this group was a 25-year low, yet the July 1, 1988 population of this age group is slightly higher than its 1980 population." (DB)
