New subject: County-to-county worker flow data, 2000

3 Jun 2003

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.

...
  Colleagues, Elaine Murakami at FHWA has suggested I
contact you. I
 am working on a county-to-county work flow analysis for North Carolina's 100
...
  counties, and am interested to know if anyone is/has
done something similar
...
  for cities or for other states or US regions. The
issues we are  addressing
...
  are:
 1. Has inter-county commuting increased as a share of trips, VMT, and  fuel
...
  use since 1990?
 2. What percent of state travel and fuel use is in intra- and  inter-county
...
  commuting? Is it a declining or increasing share?
 My student (Ellen Cervera) has completed the first phase of her
 work, for 2000, and is beginning the 1990 analysis. Her problem involves
 computing, for all NC co-to-co flows (100*100), the % of vehicle trips
 (adjusted for carpooling), the % of VMT (using a distance matrix and 20  %
...
  road circuituity), and % of fuel use (using weighted
fuel rates from Hy
 Statistics VM-1) that is inter-co versus intra-co; also these %'s as a
 function of total state use, and changes in these %'s from 1990 to 2000. The
...
  effects are hypothesized to be compensating: that is,
trips are getting
 longer and the % of travel that is inter-county is increasing, but fuel use
...
  is declining per mile, so the magnitude of fuel use in
inter-county may  be
...
  stable or declining over time. My modeling system is

 Anyone working on a similar problem with the 2000 county-to-county
 data? We would appreciate receiving materials at this location or at fax
