I think in any given year, thousands and even hundreds of thousands leave any big state for many reasons. This has been going on for some time, but only in the last decade or so has this been getting all the headlines.
Yep and it has very little to do with the political climate. Most people move for family, health, or work reasons. And the bigger the state’s population, the more that move.
I would agree with you....year-by-year, you can spot various trends. In fact, going back 30, 50 and even 100 years ago...there were yearly trends going on....just no data to state it as a fact.
People are more mobile today...than any point in the past fifty years.
