ZIP 94066 vs ZIP 94080

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