Comparing regional and subregional division characteristics of public elementary and secondary education in the United States, this report presents selected key statistics for each of the 50 states, the District of Columbia, and 5 outlying areas. This report is based on responses to the "Public Elementary and Secondary School Universe" and the "Public Elementary and Secondary Education Agency Universe" surveys received from state education agencies in the spring and summer of 1989. Information for the school year 1988-89 is presented on the public schools by state, including: elementary and secondary schools; racial/ethnic composition of schools; students; teachers; and state agencies. A sample school universe survey form and an educational agency universe survey form are included. (KM)
