Mount Morris, MI — Flint, MI

This side-by-side compares ZIP 48458 (Mount Morris, MI) and ZIP 48505 (Flint, MI) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 48458 has a population of 20,538 at 226 people per square mile, while ZIP 48505 has 25,710 at 790 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 48458 reports a median household income of $46,797 against $33,283 in ZIP 48505, with per-capita income of $28,226 vs $18,546. The share of adults holding a bachelor's degree or higher is 8.2% in 48458 and 10.8% in 48505. Poverty rate reads 19.3% vs 39.4%, and unemployment 8.7% vs 22.6% — 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 $95,600 in 48458 versus $31,700 in 48505, with median rent of $899 and $797 per month respectively. Homeownership rate is 66.9% vs 48.3%. 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.
