Married Couple (% of all Households) by Zip Code (ZCTA5) — Michigan

NOTE: Gray indicates insufficient data or a suppressed estimate.

Suburban zip codes ringing the Detroit metro area—particularly in Oakland, Livingston, and western Wayne counties—display the highest married-couple household rates, frequently exceeding 70%, while urban cores in Detroit, Flint, Saginaw, and Lansing register the lowest percentages, often falling below 30%. The Upper Peninsula presents a relatively moderate and uniform distribution mostly in the 50–60% range, with isolated pockets of higher rates in rural western areas and lower rates near Marquette and Sault Ste. Marie. A notable urban-suburban gradient repeats across the state's mid-sized cities, including Grand Rapids, Kalamazoo, and Ann Arbor, where central zip codes contrast sharply with surrounding exurban areas.
