What is interesting is that despite their prediction of half the population living in 8 states, their prediction is that half of those states will have either lost population or have gained less than 200,000 people within the next 20 years (Pennsylvania, Illinois, Ohio, Michigan)!

Edit, I am sorry, but I misinterpreted. The 4 states I mentioned are in their prediction of the 10 states with the highest population. Only Pennsylvania and Illinois are predicted to be among the 8 most populous states.

Somehow, I'm always able to view Washington Post articles without logging in or anything, but I know others seem to have trouble...
