Zip codes in the northern and western portions of Rhode Island—particularly in areas corresponding to Burrillville, Glocester, and parts of Coventry—tend toward larger average household sizes in the 2.8–3.2+ range, consistent with more suburban and rural single-family housing stock. In contrast, Providence's urban core and the Block Island zip code register notably lower averages, dropping below 2.0, reflecting higher concentrations of single-person households, student housing, and smaller rental units. A few small zip codes show extreme values at both ends of the spectrum, including a bright yellow outlier near the southern coast suggesting a localized area with average household sizes approaching 3.5.
