I had already noted for Wheeling model development that commuting to counties in Pennsylvania doubled from 1990 to 2000!  But to address the general point, seems there's two trends at work - in stagnant regional economies, workers try to avoid moving when by choice or force they take that more distant job (in addition to all the "rural community" issues, what kind of price would you get for your house in a stagnant or declining economy?).  And in booming regions, the cost of buying a new house becomes the problem.  Lack of space and "gov'mint regulation" are the usually-cited culprits, but maybe we've also gotten to the point where NIMBYism and the "growth controls" it leads to are having an impact in the imbalance between housing supply and demand.

Dave:  This has seen rather dramatic change nationally.  Of the 13.2 million
new commuters more than half were intercounty, 6.7 meg; raising the share of
intercounty from  to 23.9% to 26.7%.  Some states have seen explosions in
this area.  Ohio, Va. etc.  A lot of this can be an accidental product of
geog.  (East vs West States) but there is something else going on -- much of
it I believe is rural workers heading to the metro suburbs for work. Note W
Va had largest increase in trav times - that wasn't congestion in
Wheeling.Also think of the car plants in the south. I recall someone saying
that all but 3 of the 104 counties in Ky sent workers to the Georgetown car
plant.   I intend to spend a lot of time on this in Commuting in America
III.   I will look forward to your work - and steal from it shamelessly.
