What the data shows in California

Across California's 58 counties, none have two or more of the four health-risk areas (environmental, disease, provider access, and social conditions) above the national threshold at once. Where need shows up here, it tends to be concentrated in a single area rather than stacking.

Statewide, the health-risk area scoring highest on average is environmental risk, the leading driver of community health need in California.

The most widespread specific risk pattern is Field Burden, triggered in 52 counties, followed by Smoke Burden in 17 counties.

Mariposa County carries the highest overall need in the state, with an opportunity score of 62 out of 100 (elevated). Higher scores mean more burden relative to the rest of the country.
