This report presents comprehensive statistics on the organization, staff, pupils, and finances of public elementary and secondary schools in the 50 states, the District of Columbia, and the outlying areas of the United States. It provides detailed data for the school year 1975-76 and historical trend data for selected items of information, in some instances going back to 1869-70. The report, in addition, gives national (but not state) enrollment figures for the following types of schools: (1) elementary and secondary departments of institutions of higher education; (2) federally operated schools on federal installations; (3) federal schools for Indians; and (4) residential schools for exceptional children. Some private school data are included for regular private correspondence schools; proprietary, vocational, and trade schools; and private schools of art, music, and dancing. Table A recapitulates the types of schools (and their respective enrollments) that operate at the elementary and secondary levels. Initial tables provide a historical summary of public school statistics; and data on school administrative units and state, local, and regional education agencies. Subsequent tables provide data on a state-by-state basis on the number of school systems, the school age population, enrollment, average daily attendance, high school graduates, instructional staff, and the school lunch program. Concluding tables present data on financing public elementary and secondary school systems, including revenue and nonrevenue receipts for public schools, total expenditures, current expenditures, capital outlays, interest on school debt, status of school bonds, value of school property, average annual salary of instructional staff, and expenditures per pupil. National totals in this report represent data summations for the states constituting the United States as of the time the data apply.
