—Not available. 1 Includes a relatively small number of secondary ungraded students. 2 Data for 1890 through 1950 are from the decennial censuses of population. Later data are Census Bureau estimates as of July 1 preceding the opening of the school year. 3 Gross enrollment ratio based on school enrollment of all ages in grades 9 to 12 divided by the 14- to 17-year-old population. Differs from enrollment rates in other tables, which are based on the enrollment of persons in the given age group only. 4 Data are for 1927–28. 5 Data are for 1940–41. 6 Estimated.   7 Projected. NOTE: Allocation of ungraded students to secondary levels based on proportions derived from prior years. Includes enrollment in public schools that are a part of state and local school systems and also in most private schools, both religiously affiliated and nonsectar­ian. Some data have been revised from previously published figures. Detail may not sum to totals because of rounding.
