ZIP 63043 vs ZIP 63146

This side-by-side compares ZIP 63043 (Maryland Heights, MO) and ZIP 63146 (Saint Louis, MO) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 63043 has a population of 22,367 at 610 people per square mile, while ZIP 63146 has 29,262 at 810 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 63043 reports a median household income of $91,509 against $84,756 in ZIP 63146, with per-capita income of $44,325 vs $53,100. The share of adults holding a bachelor's degree or higher is 45.5% in 63043 and 59.7% in 63146. Poverty rate reads 3.8% vs 7.7%, and unemployment 2.0% vs 2.9% — 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 $227,600 in 63043 versus $301,700 in 63146, with median rent of $1,283 and $1,359 per month respectively. Homeownership rate is 69.6% vs 57.5%. 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.
