<div><span class="553001418-06032009"><font face="Tahoma" color="#008000">The new Administration's policies seem to be directed towards more openess and transparency with respect to federal information - in many cases completely reversing the more restrictive
policies imposed by the previous Administration. Does this pose an opportunity to revive the questions/arguments made by the CTPP users' community in opposition to the disclosure rules promulgated after the 2000 Census?</font></span></div>

<div><span class="553001418-06032009"><font face="Tahoma" color="#008000">I don't particularly like the notion of more politicization for the Census Bureau, but I like even less (especially as a small metro area) being denied access to transportation planning
data that accounts for the uniqueness of individual communities and travel patterns. Perhaps if we again raised this issue starting now, we might get some or all of the less restrictive rules restored before the 2010 Census begins and certainly before the
time that a full Census-based CTPP would become available.</font></span></div>

<p class="MsoNormal"><font face="Courier New" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: " CourierNew??="">Dear Everyone:
<o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Courier New" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: " CourierNew??="">Today, the Census Bureau issued this Federal Register notice. The 5-year ACS is the first ACS product for small area geography, e.g. census
tracts and block groups. I have extracted KEY POINTS that will GREATLY IMPACT data availability for transportation tables and result in a lot of DATA SUPPRESSION at the tract and block group level. As this FR was just issued today, we have not had a chance
to estimate the amount of suppression that would occur given these proposed conditions.
<o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Courier New" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: " CourierNew??=""><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font face="Courier New" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: " CourierNew??="">We are currently working on profile sheets using the 2005-2007 ACS (3-year data) that was released in December 2008. We are finding many tables
to be suppressed. So, even with the population threshold of 20,000 for the 3-year ACS data, there is considerable suppression on the current ACS standard table production, at least those tables of key interest to transportation planners.
<o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Courier New" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: " CourierNew??=""><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font face="Courier New" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: " CourierNew??="">As most of you know, the first CTPP using ACS is a planned 3-year accumulation from ACS 2006-2008. The table list will be re-submitted by AASHTO
to the Census Bureau in a few weeks. <o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Courier New" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: " CourierNew??=""><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font face="Courier New" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: " CourierNew??="">The next CTPP product is envisioned as a 5-year accumulation from ACS 2006-2010. Because of the many rules the CB has established to protect
individual confidentiality not just for the ACS Standard tables, but also for custom tabulations like the CTPP, we believe that the 5-year CTPP for small area tabulation (e.g. TAZs) will need to rely on synthetic data generated inside the CB using the ACS
microdata records. <o:p></o:p></span></font></p>

<p class="MsoNormal"><font face="Courier New" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: " CourierNew??="">*Federal Register Notice: The 5-Year ACS Data Products Release Plan<o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Courier New" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: " CourierNew??=""><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font face="Courier New" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: " CourierNew??="">Today the U.S Census Bureau published its data release plan for the ACS 5-year data products in the Federal Register (E9-4803). Beginning in
late 2010, the Census Bureau plans to introduce 5-year data products covering the January 2005 through December 2009 data collection period. The release of the 5-year estimates will achieve the goal of the ACS to provide small area data similar to the long-form
sample data published after Census 2000.<o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Courier New" size="2"><span style="FONT-SIZE: 10pt; FONT-FAMILY: " CourierNew??="">The Census Bureau is proposing to modify its current line of data products to accommodate the 5-year estimates and is requesting comments from
current and potential users of ACS data products to help guide this modification.<o:p></o:p></span></font></p>
