too, though I'd think it wouldn't affect 25-34 that much. I don't know about the 25-34 age bracket - guys in Fort Mac, or just on the farm, would do it. Universities are become female-dominated places, and this probably impacts numbers a little bit too, though I'd think it wouldn't affect 25-34 that much. But not Faculties of Engineering, which are still male-dominated despite everyone's best efforts. Old joke: What do Engineers use for birth control? Their personalities. Determinant: about higher birth rates, something similar is also happening in some parts of Europe. It may be different in Canada, but the delayed maternity is the reason why this is happening in my country. The shift in the time when women usually gave birth changed from 18-28 years closer to 28-38 years. This change in behavior somewhat overstated the birth rate problem in the past and it also created a temporary blip in birth rates during recent years. But the underlying problem of natural decline is still there.
