ZIP 53121 vs ZIP 53191

This side-by-side compares ZIP 53121 (Elkhorn, WI) and ZIP 53191 (Williams Bay, WI) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 53121 has a population of 19,045 at 64 people per square mile, while ZIP 53191 has 2,842 at 283 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 53121 reports a median household income of $85,643 against $75,833 in ZIP 53191, with per-capita income of $46,804 vs $51,438. The share of adults holding a bachelor's degree or higher is 32.6% in 53121 and 48.0% in 53191. Poverty rate reads 5.9% vs 8.3%, and unemployment 1.7% vs 2.2% — 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 $313,500 in 53121 versus $414,600 in 53191, with median rent of $1,054 and $900 per month respectively. Homeownership rate is 72.1% vs 80.4%. 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.
