A new comprehensive ranking of health for nearly every county in America finds that Cobb County ranks No. 5 among 10 metro Atlanta counties and No. 7 among all Georgia counties.

The study of more than 20 health measures by the Robert Wood Johnson Foundation and University of Wisconsin Population Health Institute found that 18 percent of Cobb residents report being physically inactive, compared to 25 percent statewide.

Meanwhile, 89 percent say they have access to places where they can be physically active, nearly 15 percent higher than the statewide rate. And Cobb also has lower rates of smoking and obesity.
