ZIP 95640 vs ZIP 95642

This side-by-side compares ZIP 95640 (Ione, CA) and ZIP 95642 (Jackson, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 95640 has a population of 11,353 at 38 people per square mile, while ZIP 95642 has 7,164 at 42 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 95640 reports a median household income of $97,000 against $81,438 in ZIP 95642, with per-capita income of $32,971 vs $45,362. The share of adults holding a bachelor's degree or higher is 16.5% in 95640 and 24.6% in 95642. Poverty rate reads 6.4% vs 10.3%, and unemployment 4.9% vs 5.8% — 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 $450,500 in 95640 versus $456,100 in 95642, with median rent of $1,350 and $1,419 per month respectively. Homeownership rate is 84.1% vs 66.8%. 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.
