The US Environmental Protection Agency's (EPA) Center for Public Health and Environmental Assessment (CPHEA) in the 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 non-transformed variables chosen to represent the Air, Water, Land, Built, and Sociodemographic Domains of the total environment for 2006-2010. This does not represent the final variables for the EQI. The Transformed dataset was used to create the EQI. This dataset is for information purposes only for those who want to see the original non-transformed variables. More information about the EQI can be found at https://www.epa.gov/healthresearch/epas-environmental-quality-index-supports-public-health
