1Data 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.

2Data for 1889-90 through fall 1969 are gross enrollment ratios (GER), which are based on school enrollment of all ages in grades 9 to 12 divided by the 14- to 17-year-old population. Data for fall 1970 through fall 2021 are enrollment rates for the 14- to 17-year-old population, which compare the population in this age group with enrollment of persons in this age group only. The GER allows for comparisons over time but is not intended to provide a precise measure of enrollment for any single year. Because some high school students are younger than 14 or older than 17, the GER is likely higher than the enrollment rate for the 14- to 17-year-old population.

3Includes students reported as being enrolled in grade 13.

4Data are for 1927-28.

5Data are for 1940-41.

6Estimated.

NOTE: Data in this table represent the 50 states and the District of Columbia. 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. The enrollment for ungraded public school students was estimated based on prior reports. The enrollment of ungraded private school students was estimated based on enrollment in individual high schools. Some data have been revised from previously published figures. Detail may not sum to totals because of rounding.
