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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in the rural north-central and northern tier counties of Pennsylvania consistently display married-couple household rates in the 50–65% range, while the southeastern corner—particularly the Philadelphia metro area—exhibits stark contrasts, with urban core zip codes dropping below 20–30% and affluent suburban zip codes in Chester and Montgomery counties reaching 70–80%. The Pittsburgh metro area in the southwest mirrors this urban-suburban divide on a smaller scale, with low-percentage clusters in the city center surrounded by higher-rate suburban rings. Notably, scattered yellow-shaded zip codes (70%+) in the Lehigh Valley, Poconos, and Lancaster County likely correspond to communities with strong family-oriented demographics, including areas with significant Amish and Mennonite populations.
