ZIP 11730 vs ZIP 11739

This side-by-side compares ZIP 11730 (East Islip, NY) and ZIP 11739 (Great River, NY) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 11730 has a population of 14,712 at 743 people per square mile, while ZIP 11739 has 1,223 at 588 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 11730 reports a median household income of $145,652 against $164,286 in ZIP 11739, with per-capita income of $62,048 vs $70,270. The share of adults holding a bachelor's degree or higher is 43.0% in 11730 and 61.9% in 11739. Poverty rate reads 4.9% vs 0.0%, and unemployment 2.1% vs 4.5% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 84.7% vs 96.2%. 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.
