Notes: Air carrier data were smoothed using an exponential smoothing model, with a weight of 0.945 to reduce the year-to-year fluctuations. Air carrier fatalities resulting from the Sept. 11, 2001, terrorist attacks include only onboard fatalities.
2007 passenger car occupant, light-truck occupant, large-truck occupant, and motorcycle rider data are revised. The 1992, 1995, 1998, and 2006 data are revised for general aviation fatalities and rates.
