Demographics of contributors

It would be great to have at least the city/country in which our top ~50 contributors are based. I feel like this could be done quickly/easily from the github profiles? (@bsipocz @sosey?) Maybe we send an email to dev asking folks to update their profile. (A larger demographic survey is being led by NumFocus and is in the fund raising stage.) btw, this was motivated by a user asking to be connected to folks who are based in Australia.
