When President Obama took office in January 2009--which was the fourth month of fiscal 2009--there were 7,442,377 workers on disability, according to the Social Security Administration. As of October 2013, there was a record 8,936,932. That means the number of people on disability has increased by 1,494,555 while Obama has been in office--a jump of 20 percent.
In addition to the 8,936,932 workers collecting disability in October, there were also 157,676 spouses of disabled workers who collected additional benefits, and 1,871,127 children of disabled workers who collected benefits.
All told, 10,965,735 people collected federal disability benefits in October.
At the end of fiscal 2008, there was a net balance of $216.239 billion in the Disability Insurance Trust Fund—meaning the Treasury owed $216.239 billion in IOUs to the trust fund for surplus disability insurance tax receipts it had taken in previous years and used for other government expenses.
