If you take someplace like Japan, and assume that is not disturbed by mitrgaion, I think the total fertility rate would evolve to be quite a bit higher in about 400 years. I suspect you would go from something like 1.2 to some 1.6. A change of 0.4 is really quite large. Even a change of 0.1 would be nothing to sneeze at (what is it, one third of an SD?).
