ZIP 94580 vs ZIP 94579

This side-by-side compares ZIP 94580 (San Lorenzo, CA) and ZIP 94579 (San Leandro, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94580 has a population of 27,152 at 3,043 people per square mile, while ZIP 94579 has 20,571 at 2,540 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 94580 reports a median household income of $110,729 against $99,040 in ZIP 94579, with per-capita income of $42,879 vs $42,276. The share of adults holding a bachelor's degree or higher is 26.1% in 94580 and 28.0% in 94579. Poverty rate reads 5.5% vs 7.7%, and unemployment 5.3% vs 7.0% — 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 $846,700 in 94580 versus $850,300 in 94579, with median rent of $2,274 and $2,139 per month respectively. Homeownership rate is 71.9% vs 73.7%. 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.
