Published by U.S. Environmental Protection Agency, Research Triangle Park | U.S. Environmental Protection Agency | Metadata Last Checked: January 27, 2026 | Last Modified: 2018-08-01T00:00:00.000+00:00
The US Environmental Protection Agency's (EPA) Center for Public Health and Environmental Assessment (CPHEA) in Public Health and Environmental Systems Division (PHESD) is currently engaged in research aimed at developing a measure that estimates overall environmental quality at the county level for the United States. This work is being conducted as an effort to learn more about how various environmental factors simultaneously contribute to health disparities in low-income and minority populations, and to better estimate the total environmental and social context to which humans are exposed. This dataset contains the finalized transformed variables chosen to represent the Air, Water, Land, Built, and Sociodemographic Domains of the total environment for the 2006-2010 EQI.
