No, it is a combination of:
1) students going to school longer (not necessarily a good thing)
2) aging population
3) more people retiring early
4) people losing their jobs at the tail end of their prime working years and unable to find new jobs
5) hangover from the enormous disability claims that were approved during the great recession (bad thing)
6) probably some others I don't know about
But this is largely explained by 1 and 2 Almost 1/4th of our population is 55+
