Re: [CTPP] Opportunity for input on the upcoming CTPP

is the link different because i already forwarded you previous message to all mpo staff directors in nys? This is a little different from the Spreadsheet I sent out earlier, in that the spreadsheet is modified and there is a link to a webinar on June 7th to discuss the table request. Opportunity for input on the upcoming CTPP based on 5-year ACS 2006-2010 Here is your chance to help us make the CTPP based on ACS five-year estimates the best possible data tool for transportation planners. Help us determine our request to the US Census Bureau based on your transportation planning needs. Join us at a webinar to discuss the five-year table request <http://www.nhi.fhwa.dot.gov/resources/webconference/web_conf_learner_re g.aspx?webconfid=20448> , learn about CTPP, and let yourself be heard-June 7th, 2010, 1-3 pm eastern. The spreadsheet linked here <http://ctpp.transportation.org/Documents/Comparison%20of%20requested%20 and%20approved%203yr%20tables%20and%20prospective%205%20yr%20tables.xls> contains several elements. It combines: * Three-year CTPP * the original request for U.S. Census Bureau, American Community Survey 2005-2007 three-year estimates, Special Tabulation: Census Transportation Planning Products request * the revised and approved request for U.S. Census Bureau, American Community Survey 2006-2008 three-year estimates, Special Tabulation: Census Transportation Planning Products * Five-year CTPP * the proposed request for U.S. Census Bureau, American Community Survey 2006-2010 five-year estimates, Special Tabulation: Census Transportation Planning Products for large area geography, and * the proposed request for U.S. Census Bureau, American Community Survey 2006-2010 five-year estimates, Special Tabulation: Census Transportation Planning Products for small area geography For large area geography, we plan to keep the table list the same as the current 3-year table list. For small area geography (tract, TAZ, and block group), we are proposing to eliminate many of the tables with 3-way cross-tabulations, or 2-way cross-tabulations with more than 40 cells. If you see tables that you use on the "planning to not request" list please let me know at ctppinfo(a)aashto.org. The number of classifications in each variable may need to be reduced to pass the CB's criteria and some of those tables have been tagged in the column called Modifications to be discussed for 5-yr data table request; we are including this information to start thinking about the ways variable groups can collapse. For the ACS 2006-2010 five-year data and the 2010 Census Tracts, there is projected to be, on average, a little over 4000 residents per tract, and approximately 120 household records and 150 worker records in the unweighted sample. Each TAZ, of course, will have many fewer.
