ZIP 94115 vs ZIP 94123

This side-by-side compares ZIP 94115 (San Francisco, CA) and ZIP 94123 (San Francisco, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94115 has a population of 33,021 at 11,427 people per square mile, while ZIP 94123 has 23,088 at 8,724 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 94115 reports a median household income of $151,524 against $218,603 in ZIP 94123, with per-capita income of $115,993 vs $170,097. The share of adults holding a bachelor's degree or higher is 74.2% in 94115 and 83.9% in 94123. Poverty rate reads 13.3% vs 4.9%, and unemployment 4.6% vs 3.3% — 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 $1,679,000 in 94115 versus $2,000,001 in 94123, with median rent of $2,476 and $3,289 per month respectively. Homeownership rate is 25.6% vs 30.4%. 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.
