Source:

Menlo Park, CA — Atherton, CA

This side-by-side compares ZIP 94025 (Menlo Park, CA) and ZIP 94027 (Atherton, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94025 has a population of 40,526 at 1,307 people per square mile, while ZIP 94027 has 7,089 at 527 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 94025 reports a median household income of $216,601 against $250,001 in ZIP 94027, with per-capita income of $129,924 vs $188,761. The share of adults holding a bachelor's degree or higher is 73.3% in 94025 and 83.2% in 94027. Poverty rate reads 5.6% vs 5.3%, and unemployment 5.2% vs 3.2% — 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 94025 versus $2,000,001 in 94027, with median rent of $3,251 and $3,501 per month respectively. Homeownership rate is 58.5% vs 87.6%. 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.
