Overview

• 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.
• CalEnviroScreen ranks communities based on data that are available from state and federal government sources.
