ZIP 37221 vs ZIP 37143

This side-by-side compares ZIP 37221 (Nashville, TN) and ZIP 37143 (Pegram, TN) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 37221 has a population of 36,610 at 274 people per square mile, while ZIP 37143 has 3,818 at 53 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 37221 reports a median household income of $97,751 against $96,929 in ZIP 37143, with per-capita income of $59,079 vs $49,934. The share of adults holding a bachelor's degree or higher is 63.1% in 37221 and 32.9% in 37143. Poverty rate reads 6.3% vs 2.0%, and unemployment 3.6% vs 3.2% — 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 $463,900 in 37221 versus $392,400 in 37143, with median rent of $1,844 and $1,321 per month respectively. Homeownership rate is 70.8% vs 91.0%. 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.
