A new report suggests that which Kentucky county you live plays a role in how healthy you are.

The study from the University of Wisconsin and the Robert Wood Johnson Foundation ranks each of the nation's more than 3,000 counties.

Boone County in northern Kentucky ranked as being the healthiest among Kentucky's 120 counties. The top ten also includes Oldham, Calloway, Scott, Anderson, Woodford, Owen, Franklin, Spencer, and Fayette counties.

The counties scoring among the ten worst are dominated by Eastern Kentucky counties. Wolfe County's 120th ranking was the worst. Martin, Owsley, Harlan, Perry, Magoffin, Pike, Clay, McCreary, and Floyd counties round out the bottom ten.

The report considered health factors such as smoking, obesity, binge drinking, unemployment, child poverty and air pollution.

The study illuminates a well-known trend: The least healthy counties tend to be poor and rural, and the healthiest ones tend to be urban or suburban and upper-income.
