ZIP 10543 vs ZIP 10538

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