NOTE: Gray indicates insufficient data or a suppressed estimate.
Larger household sizes (3.0+) concentrate in the northern counties around Huntsville and the Tennessee Valley, as well as scattered rural zip codes in the central Black Belt region, likely reflecting family-oriented suburban development and multigenerational households respectively. The smallest household sizes (below 2.0) cluster notably in the Birmingham metro core, Tuscaloosa, and the Mobile coastal area, consistent with higher concentrations of single-person households in urban centers and college towns. A distinct band of moderate-to-low household sizes runs through the central Black Belt corridor, interspersed with isolated high-value outliers that may reflect small rural communities with larger family structures.
