Environmental Justice Block Groups 2023 was created from Connecticut block group boundary data located in the Census Bureau's 2022 TIGER/Line Shapefiles. The poverty data used to determine which block groups qualified as EJ communities (see CT State statute 22a-20a) was based on the Census Bureau's 2021 ACS 5-year estimate. This poverty data was joined with the block group boundaries in ArcPro. Block groups in which the percent of the population below 200% of the federal poverty level was greater than or equal to 30.0 were selected and exported as a new feature class. Data for percent population minority and percent households that have limited English proficiency from the Census Bureau's 2021 ACS 5-year estimate were then added to the remaining block groups.
