It's probably going to remain this way for some time -- the numbers might even rise. Compared to the recent past in Canada, proportionately more young people are enrolled in university degree programs (and thus in a position to consider professional schools like optometry)
AND there are more young people overall due to the so-called "echo boom" (the children of baby boomers). Taken together, this has resulted in more people at the undergrad level, and, as a trickle down effect, more people applying to professional and graduate schools. I'll bet this is similar to the scenario down in the States.
Incidently, some traditional "blue collar" jobs pay
extremely well. I personally know a young electrician and someone working on the assembly line at one of the major auto plants in Ontario (close to Detroit), with only a high school education, who both earn close to 90k/year. 90k is very good pay in Canada, btw. The guy at the car plant also has
fantastic benefits, vacation time, and overtime pay! The downside is that the auto industry has lately been reducing the number of workers and/or been having problems with the unions, so it can be unstable depending on who you are. But, I've been told that being an electrician is actually fairly safe and stable as a job prospect. NOT that I'm suggesting you consider these types of work, but I think it is interesting to note. If I weren't a girl, I would have definitely given "trades" and "blue-collar" work more consideration!!
Back to optometry.....next year might be an anomaly with significantly fewer applicants.....or maybe this year was the anomaly? It's fun playing with stats
At least you have "experience" with the application and interview process now! Good luck
