ZIP 94566 vs ZIP 94588

This side-by-side compares ZIP 94566 (Pleasanton, CA) and ZIP 94588 (Pleasanton, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94566 has a population of 40,884 at 804 people per square mile, while ZIP 94588 has 30,842 at 374 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 94566 reports a median household income of $191,155 against $191,073 in ZIP 94588, with per-capita income of $92,363 vs $84,148. The share of adults holding a bachelor's degree or higher is 68.1% in 94566 and 70.9% in 94588. Poverty rate reads 4.6% vs 6.1%, and unemployment 4.0% vs 5.9% — 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 $1,656,900 in 94566 versus $1,384,300 in 94588, with median rent of $2,642 and $3,317 per month respectively. Homeownership rate is 70.6% vs 63.1%. 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.
