The New York Times discovered something most of us in the Mitten were probably unaware of: 77 percent of Michigan's residents were born in the state, a figure rivaled only by Louisiana, whose populace consists of 79 percent Creole State natives. The reason for Michigan's numbers, NYT writes, can be tied to the decline of our auto industry:
This is how postindustrial decline affects domestic migration. Michigan used to have a significant population of people born in other Midwestern states and in places like Pennsylvania, Kentucky and North Carolina. With fewer high-paying factory jobs, fewer transplants have moved in from these states.
Michigan doesn't attract a substantial amount of migrants from the east or west coast; about 7 percent come from Ohio and other Midwest states, and about 5 percent arrived from southern states.
