Manhattan stands out as the dominant low-value cluster, with household sizes dropping below 1.8 across much of Midtown and the Upper East/West Sides, reflecting the borough's concentration of single-person and small households. The highest average household sizes—exceeding 3.0—appear in pockets of outer Queens, southeastern Brooklyn, and several northern New Jersey zip codes near Paterson and Passaic, areas typically associated with larger immigrant and multigenerational families. Staten Island and the suburban zones of Westchester and Connecticut generally fall in the mid-range (2.4–2.8), creating a clear gradient from the dense urban core outward to the more family-oriented periphery.
