The death of a spouse has been described as the most disruptive and difficult role transition that an individual confronts throughout the life course. Using data from the 1984 and 1986 waves of the Longitudinal Study of Aging conducted by the National Center for Health Statistics, we examined the probability of moving associated with changes in functional disability levels over a two-year period while controlling for recent widowhood. We found that the greater the increase in instrumental disability between 1984 and 1986, the greater the probability of a move. We also found that the event of becoming a widow greatly increases the probability of a move when health declines.
