That's not a mystery. It's all the Liberals who moved to those states, couldn't understand why the welcome wagon wasn't rolled out for them, and moved back as soon as they could. Good riddance to bad rubbish.
Could WV and Kentucky problems be Hussein's ‘War on Coal’ ????
It looks more like it's rural people who can't find work -- at least in West Virginia and Kentucky. The part of West Virginia that people are actually moving into is the part nearest DC, and most of the people moving to Mr. Rockefeller's neighborhood are most likely liberals themselves.
It is not new for WV to lose population. Remember OB is determined to kill the coal industry,
We moved to soCal from WV in 59. I noticed in the 1960 census and think a couple of times thereafter WV lost population.
On trips home, I would ask where all the young men were, after seeing all the young women rocking babies on their porches. I was told out of state college or military and they don’t come back.
