Data used here come from a national mortality database compiled by the Centers for Disease Control’s National Center for Health Statistics. Years of potential life lost (YPLL) are computed from this data by matching the ages of victims with the corresponding entries in the life expectancy tables. Remaining years of life expectancy from the age of death to 65 years are counted toward YPLL. Victims 65 years and older are not included. YPLL data for 1982 through 2000 are available online through the Web-Based Injury Statistics Query and Reporting System (WISQARS).
