Enrollment by three measures, start and end of the period

What this dataset measures

Built to check a widely shared claim that Seattle Public Schools' budget rose 96% from 2014 to 2025 while enrollment stayed near 48,500. Uses the state's year-end financial records (F-196) for every district so Seattle and the statewide total are measured the same way.

Limitations and reproducibility

Reproducible from public sources: Every figure comes from public OSPI files, SPS budget books, BLS and BEA. Sum the F-196 general fund rows for district 17001 by year (or read the OSPI 10-year workbook), divide by OSPI's per-pupil enrollment, and deflate with the September-August average of the Seattle CPI-U.

• General fund only; capital and debt-service funds are excluded.
• 2013-14 kindergarten FTE was counted mostly at half-day, which understates 2013-14 enrollment relative to later years.
• Price indexes measure consumer or government prices broadly, not school costs specifically.
• Budget-year figures (2025-26, 2026-27) can change at year end.
