For most adult disability beneficiaries, SSDI and SSI benefits make up all or most of their income. SSDI benefits serve as the main or sole source of income for about 80% of beneficiaries. About 1 in 3 SSDI or SSI beneficiaries have no other source of income.
SSDI and SSI benefits keep millions from deep poverty and homelessness. Without SSDI, an estimated one-half of beneficiaries would live in poverty, even with benefits. About 1 in 5 SSDI beneficiaries live in poverty with the majority being low income. About 43% of SSI beneficiaries live in poverty.
