Again, the way the survey was conducted, it was done for a homogenous group. It was a qualitative data survey. They were going for numbers. If there weren't enough women who committed suicide, they wouldn't be able to see the needs.
I would be shocked if you ever get enough women, with 15% representation, to be able to do a decent survey on these things and a decent study. You need to find other ways to do these kinds of studies when there are minorities. If you use the same format that applies to the male-dominated groups, you'll never get that. You need qualitative data or you need to lump it together with other first responders or compare it with the U.S. There are other ways to do it.
That requires additional resources, additional expertise. If people want to know, they can find out, but they need to put the money out for it.
