Jackson is the 22nd healthiest of North Carolina’s 100 counties, according to findings released last week by the University of Wisconsin Population Health Institute and the Robert Wood Johnson Foundation. The County Health Rankings list the overall health of counties nationwide, using a formula to measure people’s health and how long they live. Jackson County moved up four places this year; it was No. 26 the past two years. Researchers examined physical environment, social and economic factors, clinical care and health behaviors. They looked at high school graduation rates, access to healthy foods, smoking, obesity and teen births. North Carolina’s healthiest counties are Wake, Watauga, Orange, Union and Camden, according to researchers. Counties with the poorest health were Columbus, Halifax, Scotland, Roberson and Vance. In Western North Carolina, Watauga, No. 2; Transylvania, No. 12; Henderson, No. 15; Buncombe, No. 18 and Macon, No. 19; ranked above Jackson County. The data, which includes a large error margin, shows 22 percent of Jackson County adults smoke; 33 percent are obese; 25 percent are physically inactive; and 15 percent drink too much. There were fewer alcohol-related deaths in the county, 21 percent, than the state, which had 33 percent. The teen birth rate was lower here, at 27 per 1,000, than the state rate of 44 per 1,000. Jackson County ranked 61st in the state for access to clinical care, with 26 percent of residents who are uninsured. There is a ratio of one primary care doctor per 1,033 residents; one dentist per 2,748 residents and one mental health provider per 254 residents.
