ZIP 63031 vs ZIP 63042

This side-by-side compares ZIP 63031 (Florissant, MO) and ZIP 63042 (Hazelwood, MO) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 63031 has a population of 48,212 at 1,263 people per square mile, while ZIP 63042 has 19,602 at 621 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 63031 reports a median household income of $70,811 against $49,453 in ZIP 63042, with per-capita income of $35,117 vs $30,101. The share of adults holding a bachelor's degree or higher is 28.6% in 63031 and 22.8% in 63042. Poverty rate reads 10.6% vs 17.9%, and unemployment 5.4% vs 12.6% — 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 $154,300 in 63031 versus $149,400 in 63042, with median rent of $1,429 and $976 per month respectively. Homeownership rate is 72.3% vs 52.0%. 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.
