Description: The supplemental indexes offer a different perspective on community-level vulnerability. The supplemental indexes use the same EJScreen methodology but incorporate a five-factor supplemental demographic index (as opposed to the two factor demographic index which averages low income and people of color populations). The supplemental demographic index averages: % Low Income % Unemployed % Limited English Speaking% Less than High School EducationLow Life ExpectancyThe supplemental demographic index is then combined with a single environmental indicator, to display areas with the highest intersection between these socioeconomic factors and the environmental indicator. Supplemental Index = (The Environmental Indicator Percentile for Block Group)(Supplemental Demographic Index for Block Group)The supplemental indexes provide flexibility in the ways the data can be considered within EJScreen. They also increase EJScreen’s functionality and may be more relevant for use in certain situations, such as awarding grants.For more information visit https://www.epa.gov/ejscreen/ej-and-supplemental-indexes-ejscreen#EJGeodatabase downloaded and block groups extracted with state name = Delaware.

Description: An EJ index combines demographic factors with a single environmental factor. For example, the EJ index for traffic is a combination of the following populations residing in the Census block group:The traffic indicatorThe low-income populationThe people of color populationsNote that an EJ index does not combine various environmental factors into a cumulative score -- each environmental indicator has its own EJ index.EJ index = (The Environmental Indicator Percentile for Block Group)(Demographic Index for Block Group)The EJ index is higher in block groups with large numbers of mainly low-income and/or people of color residents with a higher environmental indicator value.For more information visit https://www.epa.gov/ejscreen/ej-and-supplemental-indexes-ejscreen#EJGeodatabase downloaded and block groups extracted with state name = Delaware.

Description: EJScreen is an environmental justice (EJ) screening and mapping tool that provides EPA with a nationally consistent dataset and methodology for calculating "EJ indexes," which can be used for highlighting places that may be candidates for further review, analysis, or outreach as the agency develops programs, policies and other activities. The tool provides both summary and detailed information at the Census block group level or a user-defined area for both demographic and environmental indicators. The summary information is in the form of EJ Indexes and Supplemental which combine demographic information with a single environmental indicator (such as proximity to traffic) that can help identify communities living in areas with greater potential for environmental and health impacts. The tool also provides additional detailed demographic and environmental information to supplement screening analyses. EJScreen displays this information in color-coded maps, bar charts, and standard reports. Users should keep in mind that screening tools are subject to substantial uncertainty in their demographic and environmental data, particularly when looking at small geographic areas, such as Census block groups. Data on the full range of environmental impacts and demographic factors in any given location are almost certainly not available directly through this tool, and its initial results should be supplemented with additional information and local knowledge before making any judgments about potential areas of EJ concern.
