Element Attributes
Subfield 1: Date of Birth
  • Unknown
Subfield 2: Age
  • AAA

(From a State Police Instruction Manual): Record the date of birth exactly as it appears on the driver's license. Note that unborn fetuses are not considered persons for the purposes of crash reporting.


Accurate reporting of date of birth is used to assess the effectiveness of occupant protection systems for specific age groups, and to identify the need for safety programs directed toward them. This element is also critical in providing linkage between the crash, EMS, and hospital records.
