ZIP 94578 vs ZIP 94580

This side-by-side compares ZIP 94578 (San Leandro, CA) and ZIP 94580 (San Lorenzo, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94578 has a population of 38,558 at 3,317 people per square mile, while ZIP 94580 has 27,152 at 3,043 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 94578 reports a median household income of $94,084 against $110,729 in ZIP 94580, with per-capita income of $39,983 vs $42,879. The share of adults holding a bachelor's degree or higher is 25.8% in 94578 and 26.1% in 94580. Poverty rate reads 11.7% vs 5.5%, and unemployment 5.7% vs 5.3% — 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 $823,000 in 94578 versus $846,700 in 94580, with median rent of $2,116 and $2,274 per month respectively. Homeownership rate is 44.1% vs 71.9%. 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.
