ZIP 98166 vs ZIP 98148

This side-by-side compares ZIP 98166 (Seattle, WA) and ZIP 98148 (Seattle, WA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 98166 has a population of 20,301 at 1,386 people per square mile, while ZIP 98148 has 10,010 at 1,255 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 98166 reports a median household income of $114,969 against $87,342 in ZIP 98148, with per-capita income of $66,945 vs $45,702. The share of adults holding a bachelor's degree or higher is 46.9% in 98166 and 33.7% in 98148. Poverty rate reads 10.1% vs 11.5%, and unemployment 4.8% vs 7.3% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Housing separates these two ZIPs further: median home value sits at $824,400 in 98166 versus $607,900 in 98148, with median rent of $1,782 and $1,816 per month respectively. Homeownership rate is 67.9% vs 50.5%. 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.
