ZIP 94586 vs ZIP 94566

This side-by-side compares ZIP 94586 (Sunol, CA) and ZIP 94566 (Pleasanton, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94586 has a population of 925 at 6 people per square mile, while ZIP 94566 has 40,884 at 804 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 94586 reports a median household income of $204,931 against $191,155 in ZIP 94566, with per-capita income of $93,021 vs $92,363. The share of adults holding a bachelor's degree or higher is 50.0% in 94586 and 68.1% in 94566. Poverty rate reads 4.3% vs 4.6%, and unemployment 5.6% vs 4.0% — 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 $1,511,000 in 94586 versus $1,656,900 in 94566, with median rent of $3,501 and $2,642 per month respectively. Homeownership rate is 83.1% vs 70.6%. 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.
