ZIP 51104 vs ZIP 51101

This side-by-side compares ZIP 51104 (Sioux City, IA) and ZIP 51101 (Sioux City, IA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 51104 has a population of 22,104 at 1,099 people per square mile, while ZIP 51101 has 809 at 265 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 51104 reports a median household income of $75,362 against $15,300 in ZIP 51101, with per-capita income of $36,752 vs $21,580.

Poverty rate reads 10.4% vs 48.1%, and unemployment 4.6% vs 14.5% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

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.
