Written from the CDC, Medicare and HRSA data on this page. CDC PLACES 2025 release: modeled estimates for adults, not counts; “higher” and “lower” mean the California figure falls outside Williams’ likely range; at the ends of CDC’s ranges the grade could be anywhere from C− to B+.
What’s behind Williams’ grade
On seven CDC estimates for adults, Williams is healthier than 45% of U.S. towns, #567 of 847 in California. Smoking holds the grade up (fewer adults who smoke than 81% of U.S. towns); fair or poor health pulls it down (better than 12%).
Health estimates follow income closely across the country: towns with higher household incomes usually score higher (a correlation of 0.77 across 21,157 graded towns). Williams’ median household income is $90,761; among the 9,866 U.S. towns within 25% of that ($68K–$113K), it’s healthier than 29%, less than its income alone would suggest.
