This study contains counts of schools per United States census tract, ZIP code tabulation area (ZCTA), and school district from 2000 through 2018. Counts are broken down by type of school (public, charter, magnet, or private) and grade level (elementary, middle, or high). At the school district level, additional data are available on school characteristics such as district-level enrollment by race and ethnicity; numbers of teachers and counselors; teacher-student ratios; and expenditures and revenue, including per-pupil revenue.
