Columbus Grove, OH — Cairo, OH

This side-by-side compares ZIP 45830 (Columbus Grove, OH) and ZIP 45820 (Cairo, OH) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 45830 has a population of 6,228 at 25 people per square mile, while ZIP 45820 has 543 at 290 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 45830 reports a median household income of $80,897 against $83,125 in ZIP 45820, with per-capita income of $44,720 vs $33,722. The share of adults holding a bachelor's degree or higher is 26.4% in 45830 and 20.4% in 45820. Poverty rate reads 5.3% vs 6.9%, and unemployment 1.5% vs 2.0% — 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 $169,900 in 45830 versus $114,500 in 45820, with median rent of $765 and $1,023 per month respectively. Homeownership rate is 92.2% vs 86.4%. 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.
