Dakota City, NE — South Sioux City, NE

This side-by-side compares ZIP 68731 (Dakota City, NE) and ZIP 68776 (South Sioux City, NE) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 68731 has a population of 2,637 at 28 people per square mile, while ZIP 68776 has 15,447 at 287 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 68731 reports a median household income of $79,924 against $68,750 in ZIP 68776, with per-capita income of $31,348 vs $31,725. The share of adults holding a bachelor's degree or higher is 11.6% in 68731 and 14.8% in 68776. Poverty rate reads 6.3% vs 12.5%, and unemployment 4.6% vs 4.9% — 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 $205,600 in 68731 versus $179,800 in 68776, with median rent of $667 and $1,102 per month respectively. Homeownership rate is 85.0% vs 57.3%. 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.
