Who lives here

Most of this district's voting-age residents (52.5%) belong to minority groups. The largest is Black (45.3%). The Voting Rights Act can require districts that keep a minority community together so it can elect candidates it prefers, and those districts can be irregular on purpose. A district like this isn't necessarily drawn for that reason, and the site doesn't know whether this one was. Figures are from the 2020 Census. How these are counted

Cities and towns

The largest places with people in this district, from the 2020 Census. A place split between districts shows how many of its residents live in this one.

And 2 smaller places. 6% of this district's people live outside any city, town or named community. How places are counted

2024 presidential vote

Kamala Harris 69.9%, Donald Trump 30.1%

Shares of the votes for the two of them; other candidates are left out. Michigan used the same lines in 2024, so this is added up from precinct results. A precinct split between districts is divided by its House votes, so the figures are close estimates. Where the votes come from
