For nonprofits, agency staff and legislative offices
Pollution scores, state designations and regulated sites for every California tract. Live from the agencies that publish them.
9,000-odd tracts, 23 measures each, ranked against each other.
CalEPA designates disadvantaged communities from them. 35% of climate investment must reach priority populations.
The score says how many. The map says which, with each site's EPA file.
After 8 California power plants retired, nearby preterm births fell from 7.0% to 5.1%. The map shows results like this. It doesn't forecast.

95 means the tract sits above 95% of California tracts on that one measure. It isn't a concentration of anything.
It reads CalEPA's published list. Before applying for funding, confirm on CARB's Priority Populations map.
No "remove this facility" button. Ranks are relative, site measures are counts rather than emissions, and OEHHA rules out before-and-after use.
They show what was measured after real closures. They don't predict a number for a site here.
Six measures are counts of facilities, so a site next to a high score is partly circular.
A price next to a facility invites a causal reading the data can't back. Housing burden is already one of the 23 measures.
CalEnviroScreen is a screening tool. OEHHA says it can't assess risk to a person or an address.

The data below still works. Every record, source and caveat is the same as the map version. Only the map canvas is missing.
Table view. The interactive map needs WebGL, which this environment does not provide, so the same records are listed here instead.
