Map: Pharmacies are Detroit’s Closest Retail Amenity


In the March 2017 report, “Going the Distance: Big Data on Resident Access to Everyday Goods” the J.P. Morgan Chase Institute identified pharmacies as leading accessibility point for Detroit residents. The report compared data for both New York City and Detroit and found that in both cities the majority of residents shopped for retail goods outside of their 20-min neighborhood area.

Pharmacies came in at #1 with an average distance of 0.9 miles away with grocery stores a close #2 at 1.4 miles on average. The analysis was run with ZIP code filling in for neighborhood and ZIP code centroid being used to calculate distance which causes some issues when trying measuring distance of residents to retailers. The analysis was limited by ZIP code due to use of a credit/debit transaction database that only geotags ZIP code.
