ZIP 94510 vs ZIP 94591

This side-by-side compares ZIP 94510 (Benicia, CA) and ZIP 94591 (Vallejo, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94510 has a population of 27,088 at 374 people per square mile, while ZIP 94591 has 53,042 at 949 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 94510 reports a median household income of $121,204 against $104,550 in ZIP 94591, with per-capita income of $63,686 vs $46,935. The share of adults holding a bachelor's degree or higher is 47.6% in 94510 and 31.9% in 94591. Poverty rate reads 7.6% vs 9.8%, and unemployment 4.5% vs 8.0% — 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 $810,000 in 94510 versus $630,500 in 94591, with median rent of $2,280 and $2,288 per month respectively. Homeownership rate is 69.5% vs 66.8%. 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.
