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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Northern Alabama zip codes, particularly in the rural areas between Huntsville and the Tennessee border, consistently display higher married-couple household rates in the 60–80% range, while the central belt running through Birmingham and the Black Belt region to its south exhibits notably lower rates, frequently falling below 30%. Scattered high-value outliers appear in suburban zip codes ringing major metro areas like Birmingham, Montgomery, and Mobile, suggesting a strong suburban-urban divide in household composition. The Black Belt counties stretching from west-central to east-central Alabama form the most pronounced cluster of low married-couple percentages in the state, aligning closely with well-documented patterns of poverty and demographic composition in the region.
