What the data shows in Louisiana

Across Louisiana's 64 counties, 12 have two or more of the four health-risk areas (environmental, disease, provider access, and social conditions) above the national threshold at the same time. These are the places where several pressures land together rather than one at a time.

Statewide, the health-risk area scoring highest on average is social and economic conditions, the leading driver of community health need in Louisiana.

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

Tensas Parish carries the highest overall need in the state, with an opportunity score of 81 out of 100 (high). Higher scores mean more burden relative to the rest of the country.

Louisiana CHNA Data: The Famous Environmental Corridor Is Not Where the State's Health Risks Converge
23 of Louisiana's 64 parishes show multiple health risks running high at once, and almost none are in the industrial corridor everyone knows. The convergence lives in the Delta, where diabetes reaches 25% of adults and all 23 flagged parishes are heat-vulnerable at high confidence.
