From what amounts to a press release:
After waiting an average of 583 days for their Social Security disability hearings, 1.1 million Americans will likely face another months-long wait before receiving the judge’s decision, according to Allsup. ... A review of Allsup data shows the wait time to learn if former workers will or won’t receive the insurance benefit now averages 78 days.
The wait time for post-hearing decisions to be issued has increased from an average 56 days in the fourth quarter of 2015 to 78 days in the first quarter of 2017, according to Allsup data. Social Security disability claimants are waiting an average 19 months to receive a hearing, and they do not receive their final decision until after the hearing, when the administrative law judge (ALJ) issues the results.
