This document, the 40th in a series, presents public school statistical data for the 50 states and the District of Columbia. The data consist of estimates for the 1981-82 school year and revisions of the data for the 1980-81 school year. The statistics presented are regression-based estimates of over 30 educational statistics that have been verified or revised by state departments of education. The data analyzed for both years include the number of elementary and secondary schools; school-age population and enrollment; average daily membership and average daily attendance in public schools; the number of high school graduates; the number of instructional staff members in public schools, by type of position; average annual salaries of total instructional staff and of classroom teachers; revenue and nonrevenue receipts; and public school expenditures. National totals for all the data are presented in one table; a second table summarizes the essential school finance data, broken down by states; and eleven other tables present the total information gathered in the survey in detail. The text accompanying the tables discusses the significant aspects of the findings, and comparisons of the findings with data from past years permit analyses of important trends. (Author/PGD)
