I'll have to dig up some stats, but it's been a consistent pattern in my reading on the subject over the past 20 years.

I'm not talking about 2019 to 2020/21 pandemic migration that your article covers. Those years will obviously be an outlier. I'm talking about long-term demographic trends over the past 100+ years.

Edit: A very quick google before a series of calls today: https://www.brookings.edu/research/despite-the-pandemic-narr...

It's more difficult to find stats going back 150 years quickly, but the visualized data I've seen on that is pretty striking.
