Overall, the number of disability awards has risen from 446,083 in 1980 to 573,336 in 2022. Fluctuations during that period were predominately driven by changes in the number of awards to disabled workers. In 2022, there were 509,272 awards to disabled workers; 46,326 awards to disabled adult children; and 17,738 awards to disabled widow(er)s.

The average monthly benefit awarded to disabled workers is higher than that awarded to disabled widow(er)s or disabled adult children. The reason for the difference is that disabled workers receive 100 percent of the primary insurance amount, compared with 71.5 percent for disabled widow(er)s and 50 percent for disabled adult children (if the worker is disabled or retired) or 75 percent (if the worker is deceased).

Because men have traditionally had higher earnings than women, their monthly benefit is higher. This is most obvious in the disabled-worker group. Benefits for disabled widow(er)s and disabled adult children are dependents' benefits, so their monthly benefit is a function of the worker's earnings. Therefore, a disabled widow's average benefit tends to be higher than that of a disabled widower because average earnings are higher for male workers than for female workers. Benefit amounts are about the same for men and women in the disabled adult children group.

In 2022, benefits were awarded to 509,272 disabled workers. Among those awardees, the most common impairment was diseases of the musculoskeletal system and connective tissue (34.4 percent), followed by neoplasms (13.6 percent), mental disorders (12.0 percent), diseases of the circulatory system (11.0 percent), and diseases of the nervous system and sense organs (9.5 percent). The remaining 19.5 percent of awardees had other impairments.
