"Projections of Education Statistics to 2023" is the 42nd 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 2022 and projections of enrollment, graduates, teachers, and expenditures to the year 2023. 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 2023 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. Assumptions regarding the population and the economy are the key factors underlying the projections of education statistics. NCES projections do not reflect changes in national, state, or local education policies that may affect education statistics. The following are appended: (1) Introduction to Projection Methodology; (2) Supplementary Tables; (3) Data Sources; (4) References; (5) List of Abbreviations; and (6) Glossary.
