Zip codes in Ohio's major urban cores—particularly Cleveland, Columbus, Cincinnati, Dayton, Akron, and Youngstown—display notably lower married-couple household shares, frequently falling below 30%, forming distinct dark purple clusters against their surrounding suburbs. Suburban and exurban rings around these cities, especially in areas like Delaware County north of Columbus and Geauga County east of Cleveland, exhibit the highest concentrations at 70–80%+, appearing as bright yellow patches. Rural areas across southern and southeastern Ohio generally fall in the mid-range (40–55%), with scattered pockets of higher rates in Amish-concentrated zip codes of Holmes and Wayne counties in the north-central part of the state.
