Data from the U.S. Census describe the economic and social characteristics of students enrolled in elementary, secondary, and higher education as of October 1994. At that time approximately 69.3 million persons were enrolled in regular education at nursery school through college levels. About 45.1 million of these were between the traditional school ages of 6 and 17. About 8.1 million children were enrolled in nursery school or kindergarten, and elementary school enrollment was higher than that of the previous year at about 31.5 million. High school enrollment totaled 14.6 million, up significantly from the 13.7 million of fall 1993. The annual high school dropout rate was higher, at about 5%, than that of 1993. In October 1994, 15.0 million people were enrolled in colleges across the nation, an increase from the 13.9 million of 1993. Data are shown for U.S. students for age, sex, race, Hispanic origin, marital status, family status, family income, education of the householder, labor force status, metropolitan residence, region, and mother's labor force status and education (for preprimary education).
