Social Security Disability and SSI

Social Security Disability Insurance (SSDI) and Supplemental Security Insurance (SSI) are two programs that provide disability benefits to those with severe, long-term medical conditions that prevent them from working. SSDI is for workers who paid into the Social Security system for many years; SSI is for low-income people who aren't eligible for SSDI. Both the SSDI and SSI programs use the same medical eligibility criteria for disability, and the Social Security Administration administers both programs.
