ZIP 94951 vs ZIP 94928

This side-by-side compares ZIP 94951 (Penngrove, CA) and ZIP 94928 (Rohnert Park, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94951 has a population of 4,124 at 109 people per square mile, while ZIP 94928 has 43,170 at 2,164 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 94951 reports a median household income of $106,332 against $99,280 in ZIP 94928, with per-capita income of $70,956 vs $46,113. The share of adults holding a bachelor's degree or higher is 46.5% in 94951 and 30.6% in 94928. Poverty rate reads 8.2% vs 10.5%, and unemployment 4.0% vs 5.6% — 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 $1,207,000 in 94951 versus $666,000 in 94928, with median rent of $1,904 and $2,279 per month respectively. Homeownership rate is 71.4% vs 49.9%. 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.
