ZIP 63077 vs ZIP 63084

This side-by-side compares ZIP 63077 (Saint Clair, MO) and ZIP 63084 (Union, MO) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 63077 has a population of 11,798 at 53 people per square mile, while ZIP 63084 has 17,414 at 90 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 63077 reports a median household income of $56,281 against $75,992 in ZIP 63084, with per-capita income of $29,584 vs $33,479. The share of adults holding a bachelor's degree or higher is 15.3% in 63077 and 21.6% in 63084. Poverty rate reads 10.9% vs 7.4%, and unemployment 7.2% vs 5.5% — 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 $178,200 in 63077 versus $226,900 in 63084, with median rent of $957 and $855 per month respectively. Homeownership rate is 69.8% vs 71.3%. 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.
