§ Data from five annual surveys were combined to increase sample sizes and produce more reliable estimates. Estimates are age adjusted using the projected 2000 U.S. population as the standard population and using four age groups: 18--24 years, 25--44 years, 45--64 years, and ≥65 years. Estimates are based on household interviews of a sample of the civilian, noninstitutionalized U.S. population.
