What’s behind Rio Vista’s grade
On seven CDC estimates for adults, Rio Vista is healthier than 54% of U.S. towns, #488 of 847 in California. Mental distress holds the grade up (fewer adults with frequent mental distress than 89% of U.S. towns); diabetes pulls it down (better than 13%).

Rio Vista’s median household income is $89,306; among the 10,020 U.S. towns within 25% of that ($67K–$112K), it’s healthier than 44%, so it sits below most towns with similar incomes, too.
