South Sioux City, NE — Sioux City, IA

This side-by-side compares ZIP 68776 (South Sioux City, NE) and ZIP 51103 (Sioux City, IA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 68776 has a population of 15,447 at 287 people per square mile, while ZIP 51103 has 17,453 at 639 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 68776 reports a median household income of $68,750 against $58,197 in ZIP 51103, with per-capita income of $31,725 vs $27,717. The share of adults holding a bachelor's degree or higher is 14.8% in 68776 and 18.0% in 51103. Poverty rate reads 12.5% vs 21.0%, and unemployment 4.9% 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 57.3% vs 65.6%. 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.
