This is about the U.S. as a whole tho. I don’t think people are leaving the U.S. entirely
Based on the news I’ve been following, a more likely explanation is that Biden’s immigration policy has been more welcoming on the southern border at the same time as Latin America destabilizing quite a bit politically and generating a lot of refugee migration.
I just don’t see how high COL or lack of housing being built explains the population growth being dominated by Hispanics.
