But we wanted to go deeper and get more precise numbers. So, we matched Census net migration data from mid-2020 through mid-2022 for all the nation’s 3,000-plus counties (or their equivalents) and compared that with how these counties voted in 2020. Our working assumption is that the results of the incredibly divisive 2020 election would be a good barometer of the devoutly held political views in those counties.

What we found was striking: There has been a vast migration out of counties that voted for Joe Biden into those counties that voted to reelect Donald Trump.

Census data show a net internal migration of almost 2.6 million (2,584,459 to be exact) from blue counties to red since Biden was elected. (These figures don’t count immigrants or births or deaths, just those Americans moving from one location to another.)

[This is a free-market phenomenon in which Americans can choose their preferred political context. It’s likely to harden states in both markets and make them even less open to persuasion. This may be less a political divorce than political trench warfare, and like most instances of the latter, it will likely last a very, very long time. — Ed]
