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 Heat-Dialysis Vulnerability in 50 counties.

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.
