ZIP 02830 vs ZIP 02858

This side-by-side compares ZIP 02830 (Harrisville, RI) and ZIP 02858 (Oakland, RI) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 02830 has a population of 5,976 at 120 people per square mile, while ZIP 02858 has 570 at 381 per square mile. That difference in population size and density alone reshapes how every other metric should be interpreted — a higher-income ZIP with 1,200 residents behaves very differently from one with 45,000.

On income and education, ZIP 02830 reports a median household income of $121,111 against $128,568 in ZIP 02858, with per-capita income of $48,557 vs $34,154. The share of adults holding a bachelor's degree or higher is 27.0% in 02830 and 19.0% in 02858. Poverty rate reads 5.3% vs 0.0%, and unemployment 4.5% vs 0.0% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 82.7% vs 46.2%. When reading the comparison table below, focus on paired metrics rather than single winners — a ZIP with lower home values and lower income is not strictly "worse" if rent-to-income ratios and commute times land in the same zone. Every value is pulled from the exact same ACS table so the two columns are genuinely comparable.
