A new study ranking US counties based on health finds Tolland county is CT’s healthiest for outcomes and Middlesex for health factors. Windham is the least healthy for both outcomes and health factors. Outcomes measured include premature death, fair or poor health status, and low birthweight. Health factors include smoking, uninsurance and liquor store density. The study was released by the Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute; they plan to repeat the rankings annually.
