Service Description: The EJI uses data from the U.S. Census Bureau, the U.S. Environmental Protection Agency, the
U.S. Mine Safety and Health Administration, and the U.S. Centers for Disease Control and
Prevention to determine the cumulative impacts of environmental injustice for over 71,000 U.S.
census tracts. The EJI ranks each tract on 36 environmental, social, and health factors and
groups them into three overarching modules and ten different domains. The overall EJI score is
calculated by summing the ranked scores of three modules: the Environmental Burden Module,
the Social Vulnerability Module, and the Health Vulnerability Module. Each module represents
an important aspect of cumulative impacts as defined above. The final EJI ranking is, then,
produced using this score.
How do I interpret the EJI score for a census tract?
A percentile ranking represents the proportion of tracts (or counties) that are equal to or lower than a tract of interest in environmental burden. For example, a EJI ranking of 0.85 signifies that 85% of tracts in the nation likely experience less severe cumulative impacts from environmental burden than the tract of interest, and that 15% of tracts in the nation likely experience more severe cumulative impacts from environmental burden.
