NOTES: Not all graph scales are comparable. 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. Highway fatality rates for 1999 through 2008 are revised.
