Shelton, WA — Union, WA

This side-by-side compares ZIP 98584 (Shelton, WA) and ZIP 98592 (Union, WA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 98584 has a population of 36,630 at 42 people per square mile, while ZIP 98592 has 1,764 at 39 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 98584 reports a median household income of $78,610 against $138,370 in ZIP 98592, with per-capita income of $37,190 vs $61,225. The share of adults holding a bachelor's degree or higher is 20.3% in 98584 and 48.2% in 98592. Poverty rate reads 14.7% vs 0.9%, and unemployment 5.9% vs 3.2% — 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 $393,000 in 98584 versus $558,400 in 98592, with median rent of $1,315 and $3,501 per month respectively. Homeownership rate is 79.8% vs 83.3%. 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.
