Percentages of people needing assistance with instrumental ADLs and basic ADLs in the young-old years and over age 75: Although in the sixties and early seventies the fraction of people with ADL difficulties is relatively small, the risk of having these problems escalates dramatically over age 75. (Over age 85, roughly 1 in 6 people living in the community have a basic ADL problem.)
