45 minutes driving from 45-min driving from 42.3314, -83.0458, traced against Michigan.

Forty-five minutes driving from the Dearborn-area origin covers 4,085,488 people at 860.8 per square mile across 4,745.9 square miles. The ring stays inside Michigan and spans Detroit's urban core, the inner-ring suburbs, and the Oakland and Macomb outer tiers.

Detroit's commute-shed holds 4.09 million people with a voting-age population of 3.21 million, 61.3% white and 24.3% Black. Hispanic residents make up 5.3% and Asian residents 5.7%, with a non-Hispanic white share of roughly 56%. The Black population concentrates in the urban core while the Oakland and Macomb outer suburbs pull the aggregate white share up — one demographic envelope covering three distinct political environments.

MI-13 shifted 10.5 points right to land at D+41.0, the largest swing in the table. Wayne County moved 8.1 points right to D+29.0 over the same span. Michigan overall sits at R+1.4 after a 1.2-point rightward drift — an order of magnitude smaller than either Detroit-anchored row. The urban core and its county are sliding right in tandem while the state barely budged.
