ZIP 94040 vs ZIP 94043

This side-by-side compares ZIP 94040 (Mountain View, CA) and ZIP 94043 (Mountain View, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94040 has a population of 32,996 at 3,455 people per square mile, while ZIP 94043 has 28,358 at 1,026 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 94040 reports a median household income of $187,781 against $203,298 in ZIP 94043, with per-capita income of $119,297 vs $106,684. The share of adults holding a bachelor's degree or higher is 78.3% in 94040 and 71.1% in 94043. Poverty rate reads 6.0% vs 4.7%, and unemployment 3.7% 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 $2,000,001 in 94040 versus $1,641,100 in 94043, with median rent of $3,089 and $3,125 per month respectively. Homeownership rate is 36.8% vs 45.3%. 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.
