@gatto raised an interesting question. This is also making me wonder about how results from counties are being viewed vs. states or major metro areas :
I’m not sure this “Big Sort” view of migration fits with reports on why people are moving, decreasing populations in some cities/states, and the impact on political parties/upcoming elections. Does it seem odd to anyone else? I found examples from before and after the pandemic started, since that’s cited as a major motivating factor (for economic and/or political reasons).
