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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in the upstate and northwestern regions of South Carolina consistently display higher married-couple household percentages, often exceeding 60%, with several pockets reaching above 70–80%, particularly in suburban areas around Greenville and along the I-85 corridor. In contrast, the Lowcountry and Pee Dee regions—especially urban cores around Columbia, Charleston, and Orangeburg—exhibit markedly lower rates, frequently falling below 30–40%, reflecting higher concentrations of single-person and non-married households. The coastal zone presents a mixed pattern, with resort and retirement communities showing moderately elevated married-couple rates adjacent to lower-income areas with substantially depressed figures.
