For all persons, RADAY2WK reports the number of days in the past two weeks, other than those spent in bed or lost from work or school, on which the person cut down on the things that she or he usually does because of illness or injury.

RADAY2WK was introduced in 1968 as part of a series of variables used to determine if an illness or injury has caused persons to restrict their usual activities during the two-week reference period. For more information please use the search function and IPUMS NHIS drop-down menus.
