The main difference between Social Security Disability ( SSD , or SSDI ) and Supplemental Security Income ( SSI ) is the fact that SSD is available to workers who have accumulated a sufficient number of work credits , while SSI disability benefits are available to low-income individuals who have either never worked or who haven't earned enough work ...
