    <idPurp>To summarize environmental quality for each county of the United States; to compare environmental profiles across US counties; use as a broad environmental exposure variable for health studies; use to control for co-occurring environmental hazards when attempting to isolate the effect of a single factor.</idPurp>
    <idAbs>The US Environmental Protection Agency's (EPA) Center for Public Health and Environmental Assessment (CHPEA) 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 Environmental Quality Index (EQI), and an index for each of the associated domains (air, water, land, built environment, and sociodemographic environment). Indices are at the county level for all counties in the United States for 2006-2010. More information about the EQI can be found at https://www.epa.gov/healthresearch/epas-environmental-quality-index-supports-public-health</idAbs>

    <overview>
      <eaover>This dataset contains 2006-2010 EQI values. The domain indices are: AIR INDEX: Output from a principle components analysis using 43 air pollutant variables, including both criteria and hazardous air pollutants. This index summarizes average air exposures from 2006-2010 for each county in the United States; WATER INDEX: Output from a principle components analysis using 51 water quality variables, including water impairment, waste permits, domestic water source, deposition for 6 pollutants, drought status, 39 chemical contaminants, and 1 microorganism. This index summarizes average water quality measures from 2006-2010 for each county in the United States; LAND INDEX: Output from a principle components analysis using 18 land quality variables, including pesticides, general agriculture, facilities counts, mine data, and radon rankings. This index summarizes average land quality measures from 2006-2010 for each county in the United States; BUILT INDEX: Output from a principle components analysis using 15 built environment quality variables, including street information, businesses data, highway safety information, walkability score, green space/open land, and U.S. Census data. This index summarizes average built environment quality measures from 2006-2010 for each county in the United States; SOCIODEMOGRAPHIC INDEX: Output from a principle components analysis using 12 sociodemographic quality variables, including U.S. Census, Economic Resource Service, election results, and crime data. This index summarizes average sociodemographic quality measures from 2006-2010 for each county in the United States.</eaover>
