ZIP 12520 vs ZIP 12518

This side-by-side compares ZIP 12520 (Cornwall On Hudson, NY) and ZIP 12518 (Cornwall, NY) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 12520 has a population of 3,109 at 304 people per square mile, while ZIP 12518 has 5,870 at 228 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 12520 reports a median household income of $136,797 against $101,208 in ZIP 12518, with per-capita income of $67,519 vs $50,853. The share of adults holding a bachelor's degree or higher is 53.8% in 12520 and 50.5% in 12518. Poverty rate reads 4.0% vs 6.9%, and unemployment 5.1% vs 2.5% — 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 $473,000 in 12520 versus $432,000 in 12518, with median rent of $1,471 and $1,819 per month respectively. Homeownership rate is 71.5% vs 68.1%. 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.
