ZIP 10538 vs ZIP 10543

This side-by-side compares ZIP 10538 (Larchmont, NY) and ZIP 10543 (Mamaroneck, NY) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 10538 has a population of 16,597 at 1,783 people per square mile, while ZIP 10543 has 20,135 at 1,903 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 10538 reports a median household income of $207,969 against $126,417 in ZIP 10543, with per-capita income of $147,287 vs $75,380. The share of adults holding a bachelor's degree or higher is 82.5% in 10538 and 58.1% in 10543. Poverty rate reads 3.0% vs 10.2%, and unemployment 6.1% vs 4.5% — 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 $1,266,600 in 10538 versus $729,600 in 10543, with median rent of $2,236 and $2,165 per month respectively. Homeownership rate is 78.3% vs 58.2%. 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.
