ZIP 94559 vs ZIP 94503

This side-by-side compares ZIP 94559 (Napa, CA) and ZIP 94503 (American Canyon, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94559 has a population of 27,184 at 287 people per square mile, while ZIP 94503 has 19,681 at 588 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 94559 reports a median household income of $105,188 against $121,088 in ZIP 94503, with per-capita income of $56,864 vs $43,261. The share of adults holding a bachelor's degree or higher is 39.0% in 94559 and 32.4% in 94503. Poverty rate reads 7.4% vs 9.4%, and unemployment 7.7% vs 5.6% — 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 $898,600 in 94559 versus $697,400 in 94503, with median rent of $2,079 and $2,524 per month respectively. Homeownership rate is 49.0% vs 74.3%. 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.
