ZIP 48131 vs ZIP 49270

This side-by-side compares ZIP 48131 (Dundee, MI) and ZIP 49270 (Petersburg, MI) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 48131 has a population of 6,764 at 52 people per square mile, while ZIP 49270 has 5,874 at 51 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 48131 reports a median household income of $85,747 against $94,840 in ZIP 49270, with per-capita income of $45,965 vs $46,660. The share of adults holding a bachelor's degree or higher is 34.6% in 48131 and 26.5% in 49270. Poverty rate reads 4.3% vs 5.7%, and unemployment 3.5% vs 3.7% — 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 $274,200 in 48131 versus $297,600 in 49270, with median rent of $1,243 and $918 per month respectively. Homeownership rate is 69.6% vs 92.3%. 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.
