This report shows the values for environmental and demographic indicators, EJScreen indexes, and supplemental indexes. It shows environmental and
demographic raw data (e.g., the estimated concentration of ozone in the air), and also shows what percentile each raw data value represents. These percentiles
provide perspective on how the selected block group or buffer area compares to the entire state, EPA region, or nation. For example, if a given location is at the
95th percentile nationwide, this means that only 5 percent of the US population has a higher block group value than the average person in the location being
analyzed. The years for which the data are available, and the methods used, vary across these indicators. Important caveats and uncertainties apply to this
screening-level information, so it is essential to understand the limitations on appropriate interpretations and applications of these indicators. Please see
EJScreen documentation for discussion of these issues before using reports. For additional information, see: www.epa.gov/environmentaljustice. Also, please check out the
glossary
for the EJScreen related terms.
