Definitely. Basically, there is the notion that men and women tend to, on average, choose different professions or fields of research. This absolutely can contribute to where funding is allocated to a significant degree. According to the Statistics Canada data I was looking at, it accounts for maybe one-third, or about that. Does that answer your question?
I will say that one of the things that have helped to narrow the gap is that you see less segregation. People do choose a variety of professions, and there's less of “this is what women do, and this is what men do”.
