Cincinnati, OH — Cincinnati, OH

This side-by-side compares ZIP 45231 (Cincinnati, OH) and ZIP 45218 (Cincinnati, OH) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 45231 has a population of 40,893 at 1,100 people per square mile, while ZIP 45218 has 3,846 at 919 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 45231 reports a median household income of $71,353 against $71,000 in ZIP 45218, with per-capita income of $36,975 vs $33,792. The share of adults holding a bachelor's degree or higher is 29.2% in 45231 and 33.3% in 45218. Poverty rate reads 11.7% vs 9.0%, and unemployment 4.9% vs 2.4% — 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 $176,000 in 45231 versus $179,900 in 45218, with median rent of $1,232 and $993 per month respectively. Homeownership rate is 72.6% vs 67.3%. 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.
