ZIP 94503 vs ZIP 94589

This side-by-side compares ZIP 94503 (American Canyon, CA) and ZIP 94589 (Vallejo, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94503 has a population of 19,681 at 588 people per square mile, while ZIP 94589 has 29,876 at 1,004 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 94503 reports a median household income of $121,088 against $92,735 in ZIP 94589, with per-capita income of $43,261 vs $36,693. The share of adults holding a bachelor's degree or higher is 32.4% in 94503 and 23.0% in 94589. Poverty rate reads 9.4% vs 10.2%, and unemployment 5.6% vs 6.7% — 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 $697,400 in 94503 versus $540,400 in 94589, with median rent of $2,524 and $2,219 per month respectively. Homeownership rate is 74.3% vs 59.6%. 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.
