Three Oaks, MI — Harbert, MI

This side-by-side compares ZIP 49128 (Three Oaks, MI) and ZIP 49115 (Harbert, MI) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 49128 has a population of 3,715 at 33 people per square mile, while ZIP 49115 has 294 at 85 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 49128 reports a median household income of $67,398 against in ZIP 49115, with per-capita income of $44,502 vs $47,543. The share of adults holding a bachelor's degree or higher is 27.5% in 49128 and 91.2% in 49115. Poverty rate reads 7.2% vs 8.2%, and unemployment 3.0% vs 0.0% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 83.1% vs 100.0%. 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.
