ZIP 95403 vs ZIP 95404

This side-by-side compares ZIP 95403 (Santa Rosa, CA) and ZIP 95404 (Santa Rosa, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 95403 has a population of 45,164 at 792 people per square mile, while ZIP 95404 has 39,761 at 192 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 95403 reports a median household income of $98,191 against $105,437 in ZIP 95404, with per-capita income of $46,621 vs $66,144. The share of adults holding a bachelor's degree or higher is 29.3% in 95403 and 45.3% in 95404. Poverty rate reads 9.8% vs 7.1%, and unemployment 4.9% vs 4.5% — 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 $693,000 in 95403 versus $903,900 in 95404, with median rent of $2,275 and $1,949 per month respectively. Homeownership rate is 54.8% vs 60.9%. 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.
