I am passing this question I got on to the CTPP listserve in case anyone
can add to discussion. I hope Mary does not mind--its an important
question.

To your knowledge, has anyone developed projections of inter-county
commuting patterns based on trends from 1970 to 2000 (from CTPP data
and its precursors)?
Thanks.

Mary--I have not seen any but that does not mean that someone hasn't
done it. Personally, I could think of a hundred reasons to pick at any
projections especially if I didn't like the look of the numbers but that
does not mean that the flow history wouldn't be able to add some
insights and dimension to any projections. Projections always flow
better when they appear tied to some historical context, but I digress..
.While these are not exactly projections they are some examples of how I
have seen county flows presented: Anyone others out there?
