ZIP 63109 vs ZIP 63139

This side-by-side compares ZIP 63109 (Saint Louis, MO) and ZIP 63139 (Saint Louis, MO) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 63109 has a population of 26,946 at 2,914 people per square mile, while ZIP 63139 has 22,789 at 2,261 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 63109 reports a median household income of $69,938 against $75,757 in ZIP 63139, with per-capita income of $50,768 vs $52,008. The share of adults holding a bachelor's degree or higher is 52.5% in 63109 and 51.4% in 63139. Poverty rate reads 9.9% vs 7.0%, and unemployment 2.0% vs 1.6% — 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 $264,700 in 63109 versus $209,600 in 63139, with median rent of $971 and $1,095 per month respectively. Homeownership rate is 60.9% vs 62.6%. 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.
