Every company has a presence in the city. Contrary to my own expectations, Subway is actually the chain with the largest presence in the city, with 52 locations.
As the map indicates, fast food restaurants are distributed evenly across the city – no area has been spared from a fast food restaurant. (Although it does look like the west side has a bigger grease tooth than the east side.)
In fact, if you are in Detroit, you’re never more than about a 5-minute drive – 1.5 miles – from a fast food restaurant, unless you are on the southeast corner of Belle Isle.
Unfortunately, however, this problem extends far beyond Detroit’s boarders. I tracked the same restaurants in a diverse mix of eight Detroit suburbs and the City of Grand Rapids. Shockingly, Detroit is the second-most under-served municipality. I calculated the number of fast food restaurants per 5,000 residents in each city, based 2005-2009 ACS population data.
