Many Link Match retailers were located on the city’s south and west sides. Of the 57 retailers, 39 (68.4%) were in majority non-Hispanic Black census tracts, and 5 (8.8%) were in majority Hispanic census tracts; 44 (77.2%) were in located in census tracts with a median household income lower than the city’s median in 2018 ($55,295).

Link Match retailer locations mapped to 3 environmental variables: number of grocery stores per capita in 2020, violent crime rate in 2018, and the National Walkability Index in 2017, by census tract (N = 801), Chicago, Illinois. Violent crime and grocery store location data were obtained from the Chicago Data Portal (16). Violent crime rate was defined as the number of police-reported incidents of homicide, armed robbery, and aggravated assault per 1,000 census tract residents. Per capita grocery stores was defined as the number of grocery stores per 1,000 census tract residents. Data on walkability were obtained from the US Environmental Protection Agency; the higher the National Walkability Index score (scale, 0–20), the more walkable the census tract.
