CalEnviroScreen is a mapping tool that helps identify California communities that are most affected by many sources of pollution, and where people are often especially vulnerable to pollution’s effects.
CalEnviroScreen uses environmental, health, and socioeconomic information to produce scores for every census tract in the state.
The scores are mapped so that different communities can be compared. An area with a high score is one that experiences a much higher pollution burden than areas with low scores.
This web based tool combines mapping and demographic data to calculate the total population, median household income, number of people below poverty, and ratio of park acres per 1,000 residents within a half-mile radius of any project location in California.
