ZIP 37912 vs ZIP 37921

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