The city of Detroit is divided between two districts—the 13th and the 14th. Each of those districts also contains a substantial number of other communities. A map of Michigan’s Congressional districts is at:
City boundaries are thick gold lines on this map, and district boundaries are somewhat thinner black lines. Where city boundaries coincide with a district boundary, you can see a little bit of gold on each side of the black line.
(One thing that may be a little confusing is that the cities of Hamtramck and Highland Park are entirely surrounded by Detroit, so there are gold lines where you might not expect them.)
One of my colleagues is tabulating the population data to find out how many Detroit residents are in each of these districts.
The new 13th district has 391653 residents from the city of Detroit (55.5% of the district total) and the new 14th district has 322124 residents from the city of Detroit (45.6% of the district total).
