Source:

Armonk, NY — Thornwood, NY

This side-by-side compares ZIP 10504 (Armonk, NY) and ZIP 10594 (Thornwood, NY) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 10504 has a population of 7,987 at 189 people per square mile, while ZIP 10594 has 5,117 at 791 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 10504 reports a median household income of $250,001 against $163,542 in ZIP 10594, with per-capita income of $124,238 vs $64,814. The share of adults holding a bachelor's degree or higher is 80.2% in 10504 and 47.2% in 10594. Poverty rate reads 4.6% vs 3.1%, and unemployment 2.5% vs 4.1% — 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 $1,243,100 in 10504 versus $683,200 in 10594, with median rent of $3,131 and $2,458 per month respectively. Homeownership rate is 90.1% vs 89.6%. 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.
