ZIP 11754 vs ZIP 11787

This side-by-side compares ZIP 11754 (Kings Park, 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 11754 has a population of 18,958 at 993 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 11754 reports a median household income of $123,393 against $143,101 in ZIP 11787, with per-capita income of $61,470 vs $62,426. The share of adults holding a bachelor's degree or higher is 50.6% in 11754 and 52.9% in 11787. Poverty rate reads 2.3% vs 4.8%, and unemployment 3.6% vs 3.4% — 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 $624,700 in 11754 versus $679,800 in 11787, with median rent of $1,955 and $2,330 per month respectively. Homeownership rate is 83.6% 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.
