ZIP 94930 vs ZIP 94957

This side-by-side compares ZIP 94930 (Fairfax, CA) and ZIP 94957 (Ross, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94930 has a population of 8,500 at 205 people per square mile, while ZIP 94957 has 1,332 at 450 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 94930 reports a median household income of $145,362 against $250,001 in ZIP 94957, with per-capita income of $81,981 vs $175,428. The share of adults holding a bachelor's degree or higher is 70.7% in 94930 and 82.6% in 94957. Poverty rate reads 11.0% vs 4.2%, and unemployment 10.6% vs 0.8% — 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 $1,170,000 in 94930 versus $2,000,001 in 94957, with median rent of $2,397 and $3,501 per month respectively. Homeownership rate is 69.8% vs 86.5%. 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.
