ZIP 63010 vs ZIP 63128

This side-by-side compares ZIP 63010 (Arnold, MO) and ZIP 63128 (Saint Louis, MO) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 63010 has a population of 35,439 at 629 people per square mile, while ZIP 63128 has 29,356 at 755 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 63010 reports a median household income of $79,784 against $92,359 in ZIP 63128, with per-capita income of $38,002 vs $56,137. The share of adults holding a bachelor's degree or higher is 23.9% in 63010 and 45.4% in 63128. Poverty rate reads 6.9% vs 4.7%, and unemployment 2.9% vs 4.3% — 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 $224,300 in 63010 versus $338,700 in 63128, with median rent of $1,088 and $1,193 per month respectively. Homeownership rate is 79.1% vs 79.3%. 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.
