Codes and Frequencies
For all injury/poisoning episodes that occurred in the past 3 months and for which at least one body part was reported to have been affected, IRTYPE4B reports the second type of injury on the fourth affected part of the body reported in IRBODY4. IRTYPE4A reports the first type of injury sustained on the same body part as IRTYPE4B. Persons who did not report a second injury to the body part are not recorded as NIU, but instead have a response of "no second injury reported".
IRTYPE4B is an injury-level variable.
IRTYPE4B 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.
