"Projections of Education Statistics to 2020" is the 39th report in a series begun in 1964. It includes statistics on elementary and secondary schools and postsecondary degree-granting institutions. This report provides revisions of projections shown in "Projections of Education Statistics to 2019". Included are projections of enrollment, graduates, teachers, and expenditures to the year 2020. In addition to projections at the national level, the report includes projections of public elementary and secondary school enrollment and public high school graduates to the year 2020 at the state level. The projections in this report were produced by the National Center for Education Statistics (NCES) to provide researchers, policy analysts, and others with state-level projections developed using a consistent methodology. They are not intended to supplant detailed projections prepared for individual states. This report is organized by the level of schooling with sections 1, 2, 3, and 4 covering aspects of elementary and secondary education and sections 5 and 6 covering aspects of postsecondary education. Appended are: (1) Introduction to Projection Methodology; (2) Supplementary Tables; (3) Data Sources; (4) References; (5) List of Abbreviations; and (6) Glossary. (Contains 78 tables and 28 figures.)
