What is EJScreen's EJAM tool?

EJScreen's multisite tool (EJAM) is a tool developed by the United States Environmental Protection Agency (US EPA) that makes it easy to see demographic and environmental information summarized in and across any list of places in the nation. Using this tool is like getting a typical EJScreen report, but for hundreds or thousands of places, all at the same time.

This provides interactive results and a formatted, ready-to-share report with tables, graphics, and a map. The report can provide EJ-related information about people who live in communities near any of the industrial facilities on a list, for example.










You can upload shapefiles as one of the following combinations:

  • Upload 4 files with the same name and the following extensions: .shp, .shx, .dbf, .prj
  • Upload a .zip file containing the 4 file extensions
  • Upload a .gdb.zip file containing geodatabase files
  • Required fields: geometry
  • Example of Shapefile

About this Chart

These charts show how each demographic group and environmental stressor, in the analyzed locations, compares to its US average.

Definitions

Average site = the average site's average resident (the average resident's score is calculated at each site as the site-specific population-weighted mean, and then the arithmetic mean of those site-specific scores is calculated)
Average person at these sites = the average person among all the residents who are at any one or more of the sites, counting each person only once even if they live near more than one site.


About this Chart

This chart shows the spread of indicator values across all locations in your analysis.
