Reading the San Diego numbers
What the 2021-22 NCES and FY2020 Census finance numbers say about this district.
At $22,937 per pupil the district spends 32% more than the $17,320 metro median, outspending 84% of the districts covered. Only 42 cents of each dollar ($9,592 per student) is classified as instruction, so a large share goes to support services, facilities and transport — common in districts with long bus routes or older buildings.
Money is raised locally: 65.2% of revenue comes from local sources — overwhelmingly property tax — against 24.2% from the state. That makes the district's budget move with San Diego property values and levy votes rather than with the CA legislature. Federal aid contributes 10.6%, near the typical share for a large urban district.
93,893 students across 175 schools averages 537 students per building, and the district is larger than the typical district covered here (44,998 students). Staffing is thin relative to peers: 21.9 students per FTE teacher against a 15.2 median, 6.7 students more per teacher.
Worth flagging: high spending here is bought locally. A property-tax-funded budget at this level means school quality and San Diego housing costs are tightly coupled — the tax bill on a home is effectively the school funding mechanism.
What this data covers
Read this before comparing districts.
San Diego Unified is a county-scale district, so its catchment reaches well past the San Diego city limits and these figures describe that wider area. Independently authorised charter schools, private schools and regional vocational programs are counted separately by NCES and are not in these totals. Enrollment is the 2021-22 NCES collection; dollars are the FY2020 Census F-33 survey, the latest complete national release. The two years differ, so per-pupil spending is a stable indicator rather than a live budget line.
