ZIP 48091 vs ZIP 48015

This side-by-side compares ZIP 48091 (Warren, MI) and ZIP 48015 (Center Line, MI) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 48091 has a population of 31,106 at 1,504 people per square mile, while ZIP 48015 has 8,257 at 1,862 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 48091 reports a median household income of $54,230 against $54,703 in ZIP 48015, with per-capita income of $27,903 vs $31,938. The share of adults holding a bachelor's degree or higher is 16.7% in 48091 and 16.7% in 48015. Poverty rate reads 17.2% vs 16.8%, and unemployment 8.2% vs 6.8% — 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 $149,800 in 48091 versus $156,600 in 48015, with median rent of $1,290 and $788 per month respectively. Homeownership rate is 64.9% vs 52.2%. 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.
