Data are from the US FARS (Fatality Analysis Recording System) archive that is intended to include every accident in which there was at least one fatality. Data are limited to vehicles where the front seat passenger seat was occupied. Values are given for selected variables only.

Usage

FARS

Format

A data frame with 134332 observations on the following 18 variables.

caseid

a character vector. “state:casenum:vnum”

state

a numeric vector. See the FARS website for details

age

a numeric vector; 998=not reported; 999=not known. Cases with age < 16 have been omitted

airbag

a numeric vector

injury

a numeric vector; 4 indicates death. Blanks, unknown, and “Died prior to accident” have been omitted

Restraint

a numeric vector

sex

1=male, 2=female, 9=unknown

inimpact

a numeric vector; direction of initial impact. Categories 1 to 12 describe clock positions, so that 1,11, and 12 relate to near frontal impacts; 0 is not a collision; 13: top; 14: undercarriage. 18, introduced in 2005 has been omitted, as have 404 values in additional categories for 2010. 99 denotes a missing value.

modelyr

airbagAvail

a factor with levels no yes NA-code

airbagDeploy

a factor with levels no yes NA-code

D_injury

a numeric vector

D_airbagAvail

a factor with levels no yes NA-code

D_airbagDeploy

a factor with levels no yes NA-code

D_Restraint
