Brinnon, WA — Seabeck, WA

This side-by-side compares ZIP 98320 (Brinnon, WA) and ZIP 98380 (Seabeck, WA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 98320 has a population of 1,250 at 5 people per square mile, while ZIP 98380 has 4,173 at 38 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 98320 reports a median household income of $55,893 against $125,229 in ZIP 98380, with per-capita income of $36,149 vs $50,895.

Poverty rate reads 16.6% vs 4.6%, and unemployment 8.6% vs 5.0% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 84.2% vs 87.8%. 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.
