South Milwaukee, WI — Cudahy, WI

This side-by-side compares ZIP 53172 (South Milwaukee, WI) and ZIP 53110 (Cudahy, WI) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 53172 has a population of 21,156 at 1,692 people per square mile, while ZIP 53110 has 18,320 at 1,486 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 53172 reports a median household income of $73,427 against $66,719 in ZIP 53110, with per-capita income of $36,937 vs $38,037. The share of adults holding a bachelor's degree or higher is 29.9% in 53172 and 29.1% in 53110. Poverty rate reads 13.1% vs 11.4%, and unemployment 3.6% vs 2.4% — 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 $235,700 in 53172 versus $216,500 in 53110, with median rent of $1,014 and $1,028 per month respectively. Homeownership rate is 66.8% vs 61.4%. 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.
