ZIP 57701 vs ZIP 57106

This side-by-side compares ZIP 57701 (Rapid City, SD) and ZIP 57106 (Sioux Falls, SD) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 57701 has a population of 43,462 at 237 people per square mile, while ZIP 57106 has 39,852 at 511 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 57701 reports a median household income of $56,461 against $77,580 in ZIP 57106, with per-capita income of $33,046 vs $41,243. The share of adults holding a bachelor's degree or higher is 28.6% in 57701 and 34.4% in 57106. Poverty rate reads 17.8% vs 9.2%, and unemployment 3.4% vs 2.6% — 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 $251,200 in 57701 versus $290,200 in 57106, with median rent of $961 and $1,074 per month respectively. Homeownership rate is 60.8% vs 58.8%. 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.
