A recent analysis of the Social Security Disability Insurance system yields one glaring result: SSDI claims and beneficiaries have increased dramatically in recent years. Upon closer inspection, the analysis also reveals possible reasons for the increase along with the faltering economy.
When disability benefits began, it was as a supplement to Social Security, which covered retired workers. Physically disabling accidents and severe health problems such as heart disease and cancer were the most common reason workers had to quit working before retirement and begin receiving SSDI. Now, mental disorders such as depression and PTSD and physical disorders such as back pain and joint stress are the top complaints that applicants for SSDI are citing. Those two categories alone increased from 28 percent of awards in 1981 to 54 percent in 2009.
