NATIONAL ACCIDENT SAMPLING SYSTEM GENERAL ESTIMATES SYSTEM USER'S MANUAL, 1991 FILE
The National Highway Traffic Safety Administration (NHTSA) uses data from many sources, including the National Accident Sampling System (NASS) General Estimates System (GES) which began operation in 1988. Providing data about all types of crashes involving all types of vehicles, the GES is used to identify highway safety problem areas, provide a basis for regulatory and consumer information initiatives, and form the basis for cost and benefit analyses of highway safety initiatives. The GES obtains its data from a nationally representative probability sample selected from the estimated 6.1 million police-reported crashes which occur annually. This publication is a user manual for the GES 1991 data files. The contents are as follows: Introduction; GES Operations; GES Sample Design; GES SAS (Statistical Analysis System) Files; National Estimates; GES Variable Changes: 1990 to 1991; GES Variable Definitions: Accident File, Vehicle/Driver File, and Person File; and Appendices.
