TIGER School Districts — TIGER/Line School District Boundaries
Published by U.S. Census Bureau + NCES· annual
Federally-published GIS boundaries for every elementary, secondary, and unified school district in the United States.
In Detail
TIGER/Line School District Boundaries are the authoritative GIS files published jointly by the Census Bureau and NCES, defining the geographic catchment area of every K-12 public school district. ValiFit uses these boundaries to perform spatial point-in-polygon lookups: for every census place, we determine which school district contains its centroid, enabling district-level Education ROI scoring (per-pupil ÷ grad rate) at the place level. Without TIGER boundaries, education would only be scorable at the state level — TIGER unlocks 33,900 places (95% of US census places) with district-specific scoring.
