"Only 1.1% of the state's residents were foreign-born, placing West Virginia last among the 50 states in that statistic. It also has the lowest percentage of residents that speak a language other than English in the home (2.7%)." From Wikipedia.
"Let's be more like West Virginia!" I encourage the nativists of the U.S. to adopt that as their rallying cry. Catchy!
Note also that a) West Virginia is the eastern- and northern-most member state of the Bad Stripe (most recent post here), and b) never having had as strong an agricultural component to its economy, WV's population is 3.5% African-American vs. 20.5% for VA, which by most accounts has performed slightly better.
