As of November 2013 there were 8,941,660 people drawing Disability Insurance Benefits (DIB) under the Social Security Act. As of November 2014, the most recent month for which numbers are available, there were 8,956,269 people drawing DIB, an increase of 14,609 people or less than a fifth of one percent, from the year before. By contrast, the number of people drawing DIB went up by 136,307 or 2% between November 2012 and November 2013. In each of the last two months reported, the number of people drawing DIB has actually gone down.
Social Security's Office of Chief Actuary had forecast that there would be 9,014,000 people drawing DIB by the end of 2014. Unless there was a huge jump in the number of DIB recipients last month, the forecast was off by a not insignificant number.
We'll see how 2015 and 2016 go but it's entirely possible that the number of people drawing DIB will be going down as the debate rages in 2016 on what to do about the impending exhaustion of the Disability Trust Fund. Also, it's not clear just how impending that exhaustion date will be in 2016.
