This report forecasts U.S. public school enrollments and instructional and operations expenditures by state for each year from 1978 to 1982. Enrollment predictions are for preprimary and kindergarten, elementary, secondary, special education, and ungraded classes. Instructional expenditures include textbooks and workbooks, library materials, audiovisual materials, and teaching supplies. Operation expenditures include administration, classroom teachers' salaries, plant operation and maintenance, total net current expenditures, and grand total expenditures. The report also predicts that, nationwide, public elementary-secondary school enrollment will decrease from 43.6 million in 1978 to 41.5 million in 1982. Expenditures for total instructional materials will increase from $2.1 billion in 1978 to $2.5 billion in 1982, an increase of slightly over 4 percent per year, which falls short of the current inflation rate. Expenditures for total school operations are more in line with the projected inflation rate. Enrollment in eight states will increase during the forecast period. These states are Alaska, Colorado, Hawaii, Oregon, Tennessee, Texas, Utah, and Washington. In the remaining forty-two states enrollments will decline. Nationally expenditures for teaching supplies will grow faster than expenditures for other types of instuctional materials, followed by expenditures for textbooks and workbooks. (Author/JM)
