Hauppauge, NY — Smithtown, NY

This side-by-side compares ZIP 11788 (Hauppauge, NY) and ZIP 11787 (Smithtown, NY) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 11788 has a population of 16,821 at 755 people per square mile, while ZIP 11787 has 35,772 at 920 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 11788 reports a median household income of $149,726 against $143,101 in ZIP 11787, with per-capita income of $61,757 vs $62,426. The share of adults holding a bachelor's degree or higher is 50.5% in 11788 and 52.9% in 11787. Poverty rate reads 5.1% vs 4.8%, and unemployment 5.8% vs 3.4% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 83.3% vs 87.3%. 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.
