I don't know. It's as simple as that.
As I said, over the years since the first survey I was responsible for in 1986, I've seen a change in the definition of “disability”. It's becoming much more inclusive. The definition in the accessible act is much more inclusive. I think if we run this survey again, which we're hoping to do in 2022, the number could very well increase—perhaps not as dramatically, but for sure it will continue.
Also, we talk here only about work disability, but we have to remember that disability occurs over all ages, and with our aging population we're going to see many more people age 65 and older identifying as having a disability.
