Saint James City, FL — Sanibel, FL

This side-by-side compares ZIP 33956 (Saint James City, FL) and ZIP 33957 (Sanibel, FL) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 33956 has a population of 3,776 at 89 people per square mile, while ZIP 33957 has 6,469 at 154 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 33956 reports a median household income of $69,534 against $108,644 in ZIP 33957, with per-capita income of $46,695 vs $112,881. The share of adults holding a bachelor's degree or higher is 23.9% in 33956 and 61.0% in 33957. Poverty rate reads 9.7% vs 11.6%, and unemployment 9.1% vs 5.7% — 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 $318,200 in 33956 versus $957,300 in 33957, with median rent of $2,829 and $811 per month respectively. Homeownership rate is 90.8% vs 89.9%. 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.
