The NASS GES data sets for calendar year 2006 document 56,055 crashes, involving 137,731 occupants in 98,929 vehicles, and 3,681 nonmotorists.

Please take note: GES datasets dating from calendar year 2002 include multiple response variables. Please exercise caution when comparing data to prior years. Also, as in the case of FARS, NHTSA has added parked and working vehicles (not considered traffic units) to the file. These vehicles are NOT in the ADAAS vehicle file, and the occupants if any, are in the non-motorist file.
