What’s the matter with Kansas now?

USA Today has a cool set of maps based on county-by-county population trends from 2000 through 2007. The most striking thing is that Kansas and other Great Plains states are losing people by every measure: raw population change, "natural increase" (births over deaths), migration to and from other states, and international immigration.

Massachusetts is still growing in large part because of immigration.

UPDATE: The new Census data indicate that two counties in Massachusetts have lost population since 2000: Barnstable (because deaths outnumbered births by almost 6,000) and Berkshire (because about 3,500 more Americans moved out than moved in).

As for the rest, six counties have gone up in population primarily because births outnumbered deaths (Bristol, Essex, Nantucket, Norfolk, Plymouth, and Worcester), and the other six have gone up primarily because of an influx of international immigrants (Dukes, Franklin, Hampden, Hampshire, Middlesex, and Suffolk).
