Thank you very much for the information. Now we expect better
quality of the migration statistics from the 2008 ACS survey estimates
and the Census 2010 census counts.

At the recent ACS Peer Exchange, sponsored by the FHWA/FTA
Transportation Planning Capacity Building program, held May 10-11,
Nancy Torrieri shared a paper copy of some of the question changes for
the 2008 ACS content. I just noticed that Question 14 "Did this
live in this house or apartment 1 year ago?" has a NEW line for STREET
ADDRESS, in addition to city/town; county; State; and zipcode.
If respondents complete this line, then, coding to a "real" PUMA, not
just to county should be possible.

To CTPP-News Maillist and Other Census Groupies,
Much thanks to all who shared their migpuma concerns.
The attached file defines the migpumas and the powpumas in function of
the pumas (all 5%). I downloaded it from Blodgett's Mable database.
For instance, for Illinois (17), the pumas 3501-3519 cover the City of
Chicago and pumas 3401-3414 cover the remainder of Cook County which
call suburban Cook County. The file shows that powpuma 3500 coincides
with the city of Chicago and that migpuma 3490 coincides with Cook
We at the City defined the pumas but the definitions of the powpumas
and migpumas were done by the CB. In 1990, Chicago was a migpuma but
in 2000 the CB decided it was no longer. According to Clara, no
remainders were migpumas except Los Angeles city, why not Chicago city?
I planned to extract the population sizes off all the migpumas and
that there are many migpumas that are smaller than the City of Chicago
thereby showing a lack of equal access to data. According to
"Principles and Practices for Federal Statistical Agencies" by
Martin, Straf, and Citro, federal statistical agencies have to ensure
equal access to data. Are large subcounty cities with concentrations
minority persons getting equal access to data?
