ZIP 63135 vs ZIP 63140

This side-by-side compares ZIP 63135 (Saint Louis, MO) and ZIP 63140 (Saint Louis, MO) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 63135 has a population of 21,334 at 1,314 people per square mile, while ZIP 63140 has 294 at 226 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 63135 reports a median household income of $52,328 against $45,568 in ZIP 63140, with per-capita income of $30,248 vs $30,393. The share of adults holding a bachelor's degree or higher is 24.4% in 63135 and 28.1% in 63140. Poverty rate reads 22.4% vs 33.5%, and unemployment 6.1% vs 8.4% — 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 $107,400 in 63135 versus $84,100 in 63140, with median rent of $1,170 and $885 per month respectively. Homeownership rate is 54.2% vs 23.2%. 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.
