"Projections of Education Statistics to 2026" is the 45th report in a series begun in 1964. It includes statistics on elementary and secondary schools and degree-granting postsecondary institutions. This report provides revisions of projections shown in "Projections of Education Statistics to 2025" and projections of enrollment, graduates, teachers, and expenditures to the year 2026. 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 2026 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. 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. Appendix A of this report outlines the projection methodology and describes the models and assumptions used to develop the national and state projections. The enrollment models use enrollment data and population estimates and projections from NCES, the U.S. Census Bureau, and the economic forecasting service IHS Global Inc. The models are based on the mathematical projection of past data patterns into the future. The models also use projections of economic variables from IHS Global Inc. The projections presented in this report are based on assumptions for the fertility rate, internal migration, net immigration, and mortality rate from the Census Bureau.
