Reassessing the decline in parent-child old-age coresidence during the twentieth century

A study was conducted to estimate the number of years lived in old-age coresidence with adult children through the number of life-years lived in coresidence with an adult child while aged 65 or older. The number of life-years remained relatively constant between 1900 and 1940, while the rate of coresidence declined. Life-years lived in old-age coresidence then decreased substantially between 1940 and 1990. The findings indicated that analyses of the change in familial assistance to the elderly should also consider changes in mortality.
