ZIP 94080 vs ZIP 94066

This side-by-side compares ZIP 94080 (South San Francisco, CA) and ZIP 94066 (San Bruno, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94080 has a population of 63,975 at 2,388 people per square mile, while ZIP 94066 has 41,130 at 2,592 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 94080 reports a median household income of $136,733 against $141,272 in ZIP 94066, with per-capita income of $62,585 vs $64,238. The share of adults holding a bachelor's degree or higher is 40.8% in 94080 and 44.8% in 94066. Poverty rate reads 6.7% vs 6.0%, and unemployment 2.8% vs 5.0% — 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 $1,188,700 in 94080 versus $1,207,500 in 94066, with median rent of $2,809 and $2,773 per month respectively. Homeownership rate is 58.9% vs 62.1%. 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.
