RE: [CTPP] Brainstorming about INCOME variable for thefutureCTPP(using ACS records)

At the recent ACS Peer Exchange, sponsored by the FHWA/FTA Transportation Planning Capacity Building program, held May 10-11, 2007; 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 person 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.

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 we call suburban Cook County. The file shows that powpuma 3500 coincides with the city of Chicago and that migpuma 3490 coincides with Cook County. 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 county remainders were migpumas except Los Angeles city, why not Chicago city? I planned to extract the population sizes off all the migpumas and show 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 of minority persons getting equal access to data?
