"EJScreen is EPA's environmental justice mapping and screening tool that provides EPA with a nationally consistent dataset and approach for combining environmental and socioeconomic indicators. Advanced users can download the full EJScreen datasets as raw data files. The available data includes the EJScreen as compared to the state or nation. They are available for download at the block group or tract level resolution in geodatabase (.gdb) or comma separated values (.csv) formats. There is a data dictionary spreadsheet (.xlsx) that provides a description of each of the column names. Additionally, the data is published as a feature service for users that wish to view the data within GIS software. These data downloads are recommended for users with GIS and statistical expertise, and it is essential that anyone using the raw data understand the caveats and limitations described in the EJScreen Technical Documentation."
