ZIP 63104 vs ZIP 63103

This side-by-side compares ZIP 63104 (Saint Louis, MO) and ZIP 63103 (Saint Louis, MO) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 63104 has a population of 18,656 at 2,085 people per square mile, while ZIP 63103 has 6,900 at 1,234 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 63104 reports a median household income of $68,764 against $40,943 in ZIP 63103, with per-capita income of $60,298 vs $40,134. The share of adults holding a bachelor's degree or higher is 52.0% in 63104 and 50.2% in 63103. Poverty rate reads 19.5% vs 23.1%, and unemployment 2.7% vs 4.4% — 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 $268,900 in 63104 versus $202,900 in 63103, with median rent of $1,096 and $996 per month respectively. Homeownership rate is 44.9% vs 17.5%. 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.
