[ Health Affairs] Policy attention for the uninsured has focused recently on children, despite the fact that nonelderly adults represent about three-quarters of the uninsured. Nationally, adults are 40 percent more likely than children to be uninsured and less than half as likely to have public coverage. Although their approaches differ greatly, all states cover some adults through their Medicaid programs, partially funded by a 5077 percent federal match. Using data from the National Survey of America's Families (NSAF), this paper examines how different state approaches affected the number of nonelderly adults who obtained public coverage in 1996.
