ZIP 37310 vs ZIP 37309

This side-by-side compares ZIP 37310 (Charleston, TN) and ZIP 37309 (Calhoun, TN) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 37310 has a population of 4,135 at 38 people per square mile, while ZIP 37309 has 2,138 at 22 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 37310 reports a median household income of $81,645 against $63,699 in ZIP 37309, with per-capita income of $37,262 vs $27,879. The share of adults holding a bachelor's degree or higher is 11.3% in 37310 and 15.1% in 37309. Poverty rate reads 11.2% vs 11.5%, and unemployment 2.0% vs 8.7% — 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 $270,600 in 37310 versus $172,600 in 37309, with median rent of $933 and $902 per month respectively. Homeownership rate is 83.0% vs 80.9%. 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.
