Home to Western Michigan University and a mid-sized manufacturing base, Kalamazoo County has voted Democratic by double digits in recent presidential cycles, with its urban core offsetting more competitive townships on its edges.
The Democratic margin in Kalamazoo County reached its widest at twenty points in 1964. The margin in 2024 was eighteen points — still decisive.
Kalamazoo County's loyalty is rooted in its place. Median household income of $72,532, a 76% non-Hispanic-white share, and a population of 262,375 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Bernalillo County and Monroe County.
