This is a different way to look at the data, The first column is the percentage of persons born in the State who resided in the State in 2000 (excluding persons no longer living in the 50 States and DC). The second column is that shown in the map, which is the percentage of persons resident in the State in 2000, who were born in the State.

Good list. Surprised to see rural states at the bottom. I would have thought states with large area and low population would have few people moving out.
I made a map (below) of states having a higher first column being blue and states with a higher second column being red. Looks very regionally based.
