What would the population of the Southwestern U.S. be right now if it had remained a part of Mexico?
Specifically, how much smaller would this population be in comparison to our TL?
Any thoughts on this?
Also, for the record, the reason that I am asking this question is because the Southwestern U.S.--especially (but not only) Texas and California--experienced an extremely massive population increase during the almost 170 years that they were a part of the U.S. in our TL.
