What’s behind Williston’s grade
On seven CDC estimates for adults, Williston is healthier than 4% of U.S. towns, #152 of 169 in South Carolina. Mental distress holds the grade up (fewer adults with frequent mental distress than 21% of U.S. towns); diabetes pulls it down (better than 2%).
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). Williston’s median household income is $39,484; among the 2,238 U.S. towns within 25% of that ($30K–$49K), it’s healthier than 28%, so it sits below most towns with similar incomes, too.
Where Williston compares well: binge drinking, 12.2% (U.S. 15.4%); taking blood pressure medicine (adults with high blood pressure), 82.8% (U.S. 76.5%).
