Data from the Current Population Surveys (CPS) conducted by the Bureau of the Census in March 1986 and 1987 are presented, with tabulations and a short discussion of the basic trends provided. Summary data on years of school completed by age, sex, race, and Hispanic origin are shown for 1986 and 1987. The detailed tables present data on years of school completed by persons 15-years-old and over by age, sex, race, Hispanic origin, type of residence, region of residence occupation, marital status, and education of spouse. Also, summary data are presented for the 15 largest states and metropolitan areas. The educational level of the adult population continued to move upwards in 1987, continuing the general trend that has been noted consistently in the CPS data since first produced in 1947. Educational attainment in 1987 reached a peak level not only for the entire population, but also for both sexes and White and Hispanic persons. Two appendices are (1) definitions and explanations and (2) source and reliability of estimates. Six appendix tables include information on generalized standard errors for estimated numbers of persons (total or White, Black and other), generalized standard errors of estimated percentages (total or White, Black and other), parameters and factors for calculating approximate standard errors of estimated numbers and percentages, and factors to be applied to standard errors.
