I just wanted to share a tiny nugget of wisdom I just learned on AFF2: Have you ever wondered how/why it is that you sometimes get grayed-out 'search results' boxes? At least one reason is that you have selected a geography for which data is not available. If you have selected multiple geographies, and only one of them is a 'data not available' geography, AFF2 will still give you a grayed-out search result box, and you have to start over. There is no prompt telling you when data is not available for a geographic selection, so far as I can tell. I hope this helps other users. I tried sending an e-mail to AFF2 through the 'feedback' prompt but first it told me my message was too long, then when I reduced it to within the it just refused to take my feedback anyway. Evidently they don't really want feedback. Given the abysmal quality of their product, I can see why. Jonathan Lupton Research Planner Metroplan

[CTPP] 2006-2008 CTPP Place code

by Nicholas K Tulach

Hi again, I've been working with the CTPP Place-level data lately and i noticed that the Place codes in the 2006-2008 data have changed from the 1990 and 2000 data. Has anyone dealt with this? Any ideas on how to reconcile them? Thanks, nick

[CTPP] ACS table list

by Elaine.Murakami＠dot.gov

I like to have a paper copy of the table list at my desk, rather than to try to use the keyword search on AFF2, or to find the ACS documentation somewhere on the Census Bureau website. Several people helped put this abbreviated list together. Thank you to Nathan Erlbaum for recommending that it be shared with the listserv. Remember that B08xxxxx and C08xxxxx are the "journey to work" tables, but also include household tables such as: Household size by Vehicles available; Household size by Number of Workers in Household; and Number of Workers in Household by Vehicles Available. And don't forget to sign up for our Dec 19 webinar on Data Ferrett and more tricks with AFF2. https://www.nhi.fhwa.dot.gov/resources/webconference/web_conf_learner_re g.aspx?webconfid=23950 For this link to work, you need the address to include all the way to "=23950". Sometimes the listserv software breaks up the link and doesn't have the entire address strung together. Elaine Murakami FHWA Office of Planning 206-220-4460 (in Seattle)

[CTPP] Census Geography Question

by Ed Christopher

Today i got this question from an MPO friend of mine and was hoping others on the list could help me. Anyone experiencing similar issues. ------------- Ed We have experienced the frustration of block boundaries between the 2000 Census and the 2010 Census being dramatically different within our urbanized area. Our GIS experts have had a difficult time assembling and reconciling the differences in order for us to simply compare data on a block-by block basis. Do you know if this is unique to us or are we in the same boat as others? -- Ed Christopher FHWA Resource Center Planning Team 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443 708-283-3534 (V) 708-574-8131 (C)

RE: [CTPP] Census Geography Question

by Nancy Reger

We've had the same problem- had the same problem in 2000 with changes from the 1990 block too. Sometimes for file with varying polygonal boundaries (TAZ adjustments, block groups, etc), but we've intersected geographies and generated what I call a "pieces-parts file" that has a ton of little parts, and then use the proportion of these new polygons to reallocate data among them and then recompile them. It's not the best way to do things obviously since the data are not really uniformly distributed, but it isolates the ones that are different so you have a smaller set that needs further investigation.

RE: [CTPP] Census Geography Question (Blocks)

by Patty Becker

Appropos of this entire discussion: it sounds to me like these problems, if they are problems, are the consequence of the 2000-09 effort to realign TIGER. That was the major MAF-TIGER upgrade effort of the decade. Presumably the new lines are (a) more accurate, and (b) won't change again.

Re: [CTPP] RE: 2006-2010 ACS data geography

by michael.r.ratcliffe＠census.gov

The 2006-2010 ACS data will use 2010 census geography. However, urban areas will still be those defined based on Census 2000 data (2010 Census urban areas were not available when geographic information was delivered for ACS tabulation). 2010-based PUMAs also were not available (these are being defined now). Metropolitan and micropolitan areas will be those in existence as of December 2009.
