The Census has a web page showing block relationships between the 2000 Census "tabulation blocks" and the 2010 "collection blocks." See http://www.census.gov/geo/www/2010census/rel_block.html. The tabulation blocks are the ones used to tabulate and present the data, while the collection blocks are the ones they use operationally to collect the data. I downloaded the relationship files for my area and looked at them. They don't yet reflect the newly defined tracts I submitted through PSAP (e.g., subdivisions of now-oversized 2000 tracts). The web page says, "Currently, only the Census 2000 tabulation census block to 2010 Census collection block relationship files are available. The Census Bureau has not yet defined 2010 Census tabulation blocks. Delineation of 2010 Census tabulation blocks will occur in late summer 2010, just prior to tabulation of 2010 Census data. Relationship files containing 2010 tabulation blocks will be released in 2011 to support releases of 2010 Census data products." Of course, just because the tabulation blocks won't be released until 2011 doesn't mean the tracts won't be released earlier. But I wouldn't count on it. At any rate, Federal law (P.L. 94-171) regarding redistricting that follows every Census requires the block data and geography to be available by the end of March, 2011. This will also feed into our updating of TAZ boundaries to follow 2010 Census block boundaries, to get the CTPP data for our local modeling.

They indicated any changes to the PSAP submittal would be detailed and provided for buy-off. To date, I haven't yet heard back - it would be nice to know the final boundaries and also when they'll be available for general download. I would hope they'll release the boundaries in advance of the census. I saved shapefiles of the PSAP submittal, but I am working on the assumption the census bureau will not alter the boundaries we've submitted.

Are there supposed to be updated tract and block group boundaries available from the PSAP update with this 2009 Tiger file release? If not does anyone know when these will be updated and available for download?

I ditto that one and will await a reply to the list from CTTP or appropriate person. We at the Montgomery MPO in Alabama have already made adjustments to Census 2000 TAZ and are ready to send them to TAZ-UP process person for processing so they are concurrent with 2010 Census tabulation and finalization.

I understand we will get the 2010 block data and shape files in 2011: Will the Census Bureau or any federal agency want our revised TAZ files? Has it been determined that ACS data will be tabulated into TAZ's? Does anyone know what process will be used for us to submit our TAZ files if necessary? - another TAZ-UP?

This is good news. Just yesterday I was in a meeting where the question came up. ================== The Census Bureau has released 2009 TIGER/Line Shapefiles today. Available here: http://www.census.gov/geo/www/tiger/ This will be the last public release of TIGER data until early 2011. This early 2011 release will include all of the updated 2010 tabulation geography that serves as the geographic framework for 2010 Census data tabulations (including the new 2010 Census tracts, block groups, blocks, voting districts, and much more). Around the same time as this 2011 geospatial data release, Census will be releasing the tabular data with 2010 Census population counts down to the Census block level. See the attached document for more information, including changes under consideration and a request for input. -- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443 _______________________________________________ ctpp-news mailing list ctpp-news(a)chrispy.net http://www.chrispy.net/mailman/listinfo/ctpp-news _______________________________________________ ctpp-news mailing list ctpp-news(a)chrispy.net http://www.chrispy.net/mailman/listinfo/ctpp-news ________________________________ Under Florida law, e-mail addresses are public records.
