ZIP 22031 vs ZIP 22180

This side-by-side compares ZIP 22031 (Fairfax, VA) and ZIP 22180 (Vienna, VA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 22031 has a population of 29,795 at 1,685 people per square mile, while ZIP 22180 has 23,491 at 1,562 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 22031 reports a median household income of $134,577 against $177,111 in ZIP 22180, with per-capita income of $70,000 vs $89,115. The share of adults holding a bachelor's degree or higher is 73.6% in 22031 and 76.4% in 22180. Poverty rate reads 5.9% vs 5.1%, and unemployment 3.0% vs 3.8% — 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 $723,600 in 22031 versus $941,400 in 22180, with median rent of $2,258 and $2,381 per month respectively. Homeownership rate is 48.4% vs 69.6%. 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.
