ZIP 99113 vs ZIP 99163

This side-by-side compares ZIP 99113 (Colton, WA) and ZIP 99163 (Pullman, WA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 99113 has a population of 761 at 3 people per square mile, while ZIP 99163 has 31,404 at 59 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 99113 reports a median household income of $104,643 against $48,231 in ZIP 99163, with per-capita income of $53,436 vs $33,262. The share of adults holding a bachelor's degree or higher is 49.8% in 99113 and 61.3% in 99163. Poverty rate reads 2.1% vs 28.6%, and unemployment 3.4% vs 8.0% — 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 $398,000 in 99113 versus $435,900 in 99163, with median rent of $1,281 and $1,062 per month respectively. Homeownership rate is 92.4% vs 34.7%. 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.
