Lomira, WI — Theresa, WI

This side-by-side compares ZIP 53048 (Lomira, WI) and ZIP 53091 (Theresa, WI) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 53048 has a population of 3,364 at 49 people per square mile, while ZIP 53091 has 2,018 at 30 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 53048 reports a median household income of $74,464 against $82,750 in ZIP 53091, with per-capita income of $40,952 vs $38,950. The share of adults holding a bachelor's degree or higher is 22.0% in 53048 and 18.1% in 53091. Poverty rate reads 7.8% vs 9.1%, and unemployment 1.9% vs 4.0% — 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 $239,700 in 53048 versus $208,300 in 53091, with median rent of $1,133 and $890 per month respectively. Homeownership rate is 64.9% vs 81.9%. 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.
