A national report on the health and well-being of children and teenagers shows Tennessee improved slightly but still faces challenges, especially in the care of its youngest children. The annual Kids Count report measures each state’s progress in 10 areas. This year Tennessee improved to 42nd overall from 43rd. This year’s report shows, despite some improvement, Tennessee ranks in the bottom 10 states for infant mortality, low birth weight babies, children living in poverty and teen birth rates. But high school drop-outs have decreased 45 percent and both the child and teen death rates improved.
