Where could I find the population count for the genes Vulpes (or the fox)?

I'm looking for the population count for the following vulpes: Arctic Fox, Kit Fox, Pale Fox, Bengal Fox, Blandford's Fox, Cape Fox, Corsac Fox, Tibetan Sand Fox, Ruppell's Fox, Swift Fox, Red Fox, and Fennec Fox. I'm trying to make a graph that show's the difference in the populations of these species for a school project. any help would be great thanks.
