I think you're absolutely right. Some factors will exert a positive influence on one's likelihood to travel overseas... it's probably safe to say that the higher up the socioeconomic ladder you go, the more likely people are to have travelled overseas. Also, I'd wager that people in the major gateway cities are more likely to have gone... with a good seat sale fare you can go from Toronto to Europe or from Vancouver to Asia for $600. It's much more expensive from "interior cities".
But that said, I think the general trend is that of an overall increase, if for no other reason than because the cost of overseas travel is pretty low relative to what it was 40 years ago. Imagine if economy and premium economy got lopped off all overseas aircraft and all you were left with was business class and first class prices. That's pretty much what the traveller was facing in, say, 1972.
