ZIP 94123 vs ZIP 94115

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