"The Environmental Quality Index (EQI) presents data in five domains: air, water, land, built, and sociodemographic environments to provide a county-by-county snapshot of overall environmental quality across the entire U.S. The EQI helps researchers better understand how health outcomes relate to cumulative environmental exposures that typically are viewed in isolation.
&lt;br /&gt;&lt;br /&gt;
Because the air we breathe, the water we drink, the food we eat, and the buildings around us all play a part in our overall wellbeing, researchers can use the EQI to investigate and highlight associations between environmental quality and a given health concern. By expanding research beyond singular routes of exposure and pollutants, the EQI helps provide a clearer picture of the relationship between the environment and health. To support this scientific exploration, EPA has made the EQI and its many variables open and accessible to the public. You can learn more about the EQI under downloads below.
&lt;br /&gt;&lt;br /&gt;
Since the release of the EQI 2000-2005, researchers have published multiple studies examining the relationship between overall environmental quality and health outcomes, including preterm birth, mortality, cancer incidence, asthma prevalence, physical inactivity and obesity, infant mortality, and pediatric multiple sclerosis. You can find EQI related publications below.
&lt;br /&gt;&lt;br /&gt;
EQI data can also be used by ecologists, economists, and other researchers to address questions about environmental quality. 
&lt;br /&gt;&lt;br /&gt;
At its current county-level scale, the EQI may not reveal environmental injustices seen at the local community level. However, it does highlight counties experiencing an increased burden of environmental impacts, and the domain-specific indices enable counties to assess the drivers of poor environmental quality in their counties, which could provide a foundation for targeted support to address health concerns tied to environmental quality.
&lt;br /&gt;&lt;br /&gt;
Because modifications were made to the updated EQI 2006-2010, direct comparisons between EQI 2000-2005 and EQI 2006-2010 should not be made. The two indices should not be examined as being continuous over time (e.g., if a study period covers 2004-2007, only one of the indices should be chosen or study population should be stratified by time period matched to the appropriate EQI). Furthermore, the EQI was developed for research purposes and is not meant to be a diagnostic tool. The EQI would be useful to identify potential areas of concern for counties to target future research, but it should not be used to target regulatory purposes."
