ZIP 11749 vs ZIP 11722

This side-by-side compares ZIP 11749 (Islandia, NY) and ZIP 11722 (Central Islip, NY) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 11749 has a population of 3,345 at 592 people per square mile, while ZIP 11722 has 35,177 at 1,863 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 11749 reports a median household income of $116,313 against $114,049 in ZIP 11722, with per-capita income of $46,560 vs $33,630. The share of adults holding a bachelor's degree or higher is 32.5% in 11749 and 19.3% in 11722. Poverty rate reads 7.7% vs 9.2%, and unemployment 5.5% 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 $477,400 in 11749 versus $436,600 in 11722, with median rent of $2,019 and $2,055 per month respectively. Homeownership rate is 96.0% vs 78.2%. 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.
