ZIP 10591 vs ZIP 10523

This side-by-side compares ZIP 10591 (Tarrytown, NY) and ZIP 10523 (Elmsford, NY) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 10591 has a population of 22,540 at 880 people per square mile, while ZIP 10523 has 7,444 at 795 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 10591 reports a median household income of $104,984 against $118,438 in ZIP 10523, with per-capita income of $73,007 vs $51,968. The share of adults holding a bachelor's degree or higher is 55.5% in 10591 and 50.0% in 10523. Poverty rate reads 8.2% vs 7.2%, and unemployment 5.0% vs 7.2% — 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 $681,000 in 10591 versus $588,100 in 10523, with median rent of $2,036 and $2,978 per month respectively. Homeownership rate is 48.2% vs 51.9%. 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.
