For all injury/poisoning episodes for the last past 3 months, that reportedly occurred during the past 3 months and were caused by a fall, IRFALL1 reports the first response given about how the person fell.

IRFALL1 is an injury-level variable.

IRFALL1 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.
