A longtime prison town
Ionia has been a Michigan prison town since the 1800s, and corrections still shape local employment and population figures.
Ionia has been a prison town for a very long time. The first state prison opened here in 1877. Today, several Michigan Department of Corrections facilities cluster just west of the city. They include the Ionia Correctional Facility (one of the state’s maximum-security prisons), Bellamy Creek, and the Richard A. Handlon facility. Together they’re one of the area’s biggest employers. A lot of local families have someone who works in corrections.
One practical thing to know: the prison population is counted in the census. So the official “population” of the city of Ionia runs high. It’s larger than the number of people actually living in its neighborhoods. Keep that in mind when you look at population or density figures for the area.
