ZIP 37921 vs ZIP 37912

This side-by-side compares ZIP 37921 (Knoxville, TN) and ZIP 37912 (Knoxville, TN) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 37921 has a population of 28,233 at 712 people per square mile, while ZIP 37912 has 20,673 at 737 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 37921 reports a median household income of $60,013 against $47,416 in ZIP 37912, with per-capita income of $30,928 vs $29,869. The share of adults holding a bachelor's degree or higher is 26.3% in 37921 and 21.1% in 37912. Poverty rate reads 17.2% vs 18.8%, and unemployment 3.9% vs 4.9% — 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 $226,300 in 37921 versus $210,900 in 37912, with median rent of $1,233 and $1,128 per month respectively. Homeownership rate is 59.8% vs 53.1%. 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.
