This report presents summary data on school enrollment for October 1985 and on some of the important changes in enrollment that have occurred in the past 20 years. Presented in six tables, the data are from the October school enrollment supplement to the Current Population Survey. Highlights of the report include the following findings: (1) in October 1985 there were 59.7 million persons aged 3 years old or over enrolled in school; (2) elementary, secondary, and college enrollment did not change between 1984 and 1985, but kindergarten enrollment grew; (3) significant growth in college enrollment since 1975 was attributable to increases in enrollment among older students; and (4) college enrollment among blacks remained relatively stable over the last 10 years. The report provides a brief overview of the findings, noting the impact of changing birth rates, then presents six tables providing data on recent years' enrollment rates among students by age, race, sex, national origin, and educational level. An appendix discusses the source of the data and the reliability of the estimates based upon them. (PGD)
