* Respondents were asked, "During the past 12 months . . . about how many days did illness or injury keep you in bed more than half of the day (include days while an overnight patient in a hospital)?"

† Estimates are based on household interviews of a sample of the civilian, noninstitutionalized U.S. population and are derived from the National Health Interview Survey sample adult component.
