ZIP 20120 vs ZIP 20121

This side-by-side compares ZIP 20120 (Centreville, VA) and ZIP 20121 (Centreville, VA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 20120 has a population of 40,695 at 914 people per square mile, while ZIP 20121 has 27,988 at 1,248 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 20120 reports a median household income of $152,563 against $129,947 in ZIP 20121, with per-capita income of $63,371 vs $55,491. The share of adults holding a bachelor's degree or higher is 60.4% in 20120 and 53.8% in 20121. Poverty rate reads 6.2% vs 8.8%, and unemployment 4.5% vs 3.4% — 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 $648,700 in 20120 versus $520,200 in 20121, with median rent of $2,309 and $2,289 per month respectively. Homeownership rate is 75.4% vs 70.0%. 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.
