ZIP 10577 vs ZIP 10604

This side-by-side compares ZIP 10577 (Purchase, NY) and ZIP 10604 (West Harrison, NY) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 10577 has a population of 6,552 at 376 people per square mile, while ZIP 10604 has 11,250 at 640 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 10577 reports a median household income of $250,001 against $117,014 in ZIP 10604, with per-capita income of $63,041 vs $73,387. The share of adults holding a bachelor's degree or higher is 72.6% in 10577 and 51.1% in 10604. Poverty rate reads 3.8% vs 5.3%, and unemployment 10.1% vs 5.4% — 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 $1,631,800 in 10577 versus $735,700 in 10604, with median rent of — and $2,245 per month respectively. Homeownership rate is 99.1% vs 48.9%. 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.
