ZIP 98155 vs ZIP 98125

This side-by-side compares ZIP 98155 (Seattle, WA) and ZIP 98125 (Seattle, WA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 98155 has a population of 32,778 at 1,675 people per square mile, while ZIP 98125 has 37,081 at 2,653 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 98155 reports a median household income of $131,540 against $99,868 in ZIP 98125, with per-capita income of $67,259 vs $67,288. The share of adults holding a bachelor's degree or higher is 56.5% in 98155 and 60.2% in 98125. Poverty rate reads 6.1% vs 9.8%, and unemployment 4.8% vs 4.6% — 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 $816,400 in 98155 versus $874,300 in 98125, with median rent of $2,127 and $1,908 per month respectively. Homeownership rate is 70.2% vs 45.4%. 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.
