The Environmental Quality Index (EQI) accounts for the multiple domains of the environment with which humans interact. These domains include chemical, natural, built, and sociodemographic environments that have both positive and negative influences on health. An overall EQI was created for census tracts within the contiguous United States for 2006-2010 and 2011-2015. Provided data sets include full EQI for 2006-2010 and 20011-2015, variables used to create the census tract EQI, as well as links to maps of the data.
