ZIP 94954 vs ZIP 94945

This side-by-side compares ZIP 94954 (Petaluma, CA) and ZIP 94945 (Novato, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94954 has a population of 37,365 at 233 people per square mile, while ZIP 94945 has 17,167 at 252 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 94954 reports a median household income of $113,527 against $107,790 in ZIP 94945, with per-capita income of $57,466 vs $67,050. The share of adults holding a bachelor's degree or higher is 38.4% in 94954 and 52.1% in 94945. Poverty rate reads 6.0% vs 8.4%, and unemployment 4.3% vs 6.5% — 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 $840,500 in 94954 versus $1,124,100 in 94945, with median rent of $2,554 and $2,326 per month respectively. Homeownership rate is 67.3% vs 70.4%. 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.
