For all injury episodes that occurred during the past 3 months and were transportation-related or in which the person was a pedestrian struck by a vehicle, IRMVWHO reports whether the person was injured as the driver of a motor vehicle; a passenger; a pedestrian; a bicycle or tricycle rider; or a rider of a scooter, skateboard, skates, or other non-motorized vehicle.

IRMVWHO is an injury-level variable.

IRMVWHO is part of a series of variables initiated in 1997 that systematically report persons' injuries and poisonings, the cause, what the person was doing while sustaining the injury or poisoning, and where she/he was at the time of the injury or poisoning. For related variables and additional information, please see the User note on Injuries and Poisonings or use the IPUMS NHIS search function and drop-down menus.


Beginning in 2004, the response category "Rider of a scooter, skateboard, skates, or other non-motorized vehicle" was added. Otherwise there are no comparability issues.
