California Public Schools
The canvas comes first: every public school district in California, drawn from the federal boundary files. The data layers — enrollment change, funding, teachers, achievement — are built on top of this map, Missouri-style, in phases.
THE DISTRICT MAP
School district boundaries
Hover any district for its name. Boundaries are the 2024–25 school-year files from NCES EDGE / U.S. Census TIGER.

862 districts are drawn on this map — 345 unified and 517 elementary.
How districts are drawn here. California has separate elementary and secondary school districts whose territories overlap. To keep the map readable, it shows unified districts plus elementary districts — together they tile the state exactly, with no gaps and no overlaps. The 112 secondary districts are not drawn, because they sit on top of the elementary districts rather than beside them. Data joined to this map follows the same rule.
A note about charter schools. Charter schools enroll about 11.9% of California’s public-school students, and they are not drawn individually on this map — they have no attendance boundary to draw. But in California most charter schools are authorized by local school district boards, which means they generally sit inside the district boundaries you see here and count within those districts. What this map leaves out is the school-level detail, not the students themselves. A minority are authorized at the state level and enroll across district lines.
