ZIP 15564 vs ZIP 21545

This side-by-side compares ZIP 15564 (Wellersburg, PA) and ZIP 21545 (Mount Savage, MD) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 15564 has a population of 50 at 16 people per square mile, while ZIP 21545 has 1,940 at 52 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 15564 reports a median household income of $56,250 against $60,264 in ZIP 21545, with per-capita income of $31,674 vs $31,921. The share of adults holding a bachelor's degree or higher is 21.2% in 15564 and 17.9% in 21545. Poverty rate reads 12.8% vs 15.1%, and unemployment 0.0% vs 7.0% — 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 $158,300 in 15564 versus $130,700 in 21545, with median rent of $619 and $905 per month respectively. Homeownership rate is 63.4% vs 80.4%. 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.
