The method for identifying and locating Environmental Justice communities in the HATS region was modeled from the equity analysis method developed by Delaware Valley Regional Planning Commission. The method identifies nine demographic groups (the indicators) that could be negatively impacted by the implementation of planned transportation projects. The nine indicators are: disabled, low-income, racial minority, ethnic minority, foreign-born, older adults, young people, limited English proficiency and female.
Using US Census American Community Survey 2012-2016 five-year estimates, a regional average was identified for each indicator. Using statistical analysis, census block groups were assigned a value based on their deviation from the regional average for that indicator. The sum of the value for all nine indicators is used to estimate that block group's "potential disadvantage."
