NOTE: Data in this table represent the 50 states and the District of Columbia. Data reflect reports by schools rather than by states or school districts. Percentage distribution and average enrollment calculations include data only for schools reporting enrollments greater than zero. Enrollments greater than zero were reported for 95,364 out of 98,469 schools in 2019-20. Detail may not sum to totals because of rounding. Some data have been revised from previously published figures.
