ZIP 94558 vs ZIP 94559

This side-by-side compares ZIP 94558 (Napa, CA) and ZIP 94559 (Napa, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94558 has a population of 66,830 at 73 people per square mile, while ZIP 94559 has 27,184 at 287 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 94558 reports a median household income of $113,269 against $105,188 in ZIP 94559, with per-capita income of $63,636 vs $56,864. The share of adults holding a bachelor's degree or higher is 40.1% in 94558 and 39.0% in 94559. Poverty rate reads 8.5% vs 7.4%, and unemployment 4.3% vs 7.7% — 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 $890,500 in 94558 versus $898,600 in 94559, with median rent of $2,385 and $2,079 per month respectively. Homeownership rate is 67.5% vs 49.0%. 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.
