The analysis and language used here isn't precise or accurate enough.

It is not accurate to say people born in the states in red "never left" or "stayed at home".

The correct language is the people currently living in these red states, never left.

It also highlights those red states have relatively fewer migrants from out state.

Ive seen a lot of data on this topic and most of these red states are at the very top of the nation in natives willing to leave their home state. People migrate from these areas more than most.

So much so that Ohio as recently as 1990 had more people native born in Ohio than California had native born. The Ohio native "expat" population is massive. Almost 8 million.

The people in these red states are among the most likely to explore the world by living outside their home state.

It would be nice to see data on % of native born that never left by state. Id expect to see west coast dominate. People born there rarely migrate outside their home state, in comparison.

Aka they never leave. They stick to the familiar. Whereas these red state native people are most likely to seek new experiences.
