Effective January 1957, the OASI Trust Fund pays monthly benefits to disabled children aged 18 and over of retired and deceased workers if the
disability began before age 18. The age by which disability must have begun was later changed to age 22. Effective February 1968, the OASI Trust Fund pays reduced monthly benefits to disabled widows and widowers at ages 50 and over. Effective January 1991, the requirements for the disability of the widow or widower were made less restrictive.
At the end of 2017, the OASI Trust Fund was providing monthly benefit payments to about 1,124,000 people because of their disabilities or the disabilities of children. This total includes approximately 24,000 mothers and fathers (wives or husbands under normal retirement age of
retired-worker beneficiaries and widows or widowers of deceased insured workers) who met all other qualifying requirements and were receiving unreduced benefits solely because they had disabled-child beneficiaries (or disabled children aged 16 or 17) in their care. In calendar year 2017, the OASI Trust Fund paid a total of $11,355 million to the people described above. Table
VI.H1 shows OASI scheduled benefits for disability for selected calendar years during 1960 through 2017 and estimates for 2018 through 2027 based on the intermediate set of
assumptions.
Under the intermediate assumptions, estimated total scheduled benefits from the OASI Trust Fund with respect to disabled beneficiaries will increase from $11,737 million in calendar year 2018 to $17,363 million in calendar year 2027.
In calendar year 2017, benefit payments (including expenditures for vocational rehabilitation services) with respect to disabled persons from the OASI Trust Fund and from the DI Trust Fund (including payments from the DI fund to all children and spouses of disabled-worker beneficiaries) totaled $154,181 million. Of this amount, $11,355 million, or 7.4 percent, represented payments from the OASI Trust Fund. Table
VI.H2 contains these and similar figures for selected calendar years during 1960 through 2017 and estimates for calendar years 2018 through 2027.
