Disadvantaged Communities Definition

Disadvantaged communities are communities designated by CalEPA, pursuant to Senate Bill 535 (De León), using the California Communities Environmental Health Screening Tool (“CalEnviroScreen”). CalEnviroScreen was developed by the Office of Environmental Health Hazard Assessment to identify communities in California most burdened by pollution from multiples sources and most vulnerable to its effects, taking into account socioeconomic characteristics and underlying health status. Disadvantaged communities are identified by census tract and are those that scored at or above the 75th percentile.
