Dear Mr. Christopher:
What is the purpose of the ACS, and C2SS? Is the purpose to collect data
for the sake of collecting data or seeing if the data can be collected, or
is the purpose to collect usable data? If it is to collect data for data's
sake, then $137m a year is a waste of money. If the purpose is to collect
usable data, it should be collected and distributed at a level that is
usable -- blocks, block groups, TAZs. Collecting estimates at the tract
level is a waste of time and money for most users. By the time you
manipulate the data and try to disaggregate it, you might as well take a
guess and forget about the ACS/C2SS.
If Congress wants the users to base their decisions on the data collected by
the ACS and/or the census, then the ACS/Census should collect data that can
be used to make decisions. For instance, (just one example) how are you
going to determine Title VI and Environmental Justice neighborhoods using
Tract level information?
We need a Secretary of Home Data.

Subject: [CTPP] more on what the acs may or may not give us
thanks jeff for the info. i am sure many on the list will find it
interesting. i especially liked the part about the confidentiality
thresholds--especially since there is no hard evidence of how one can
disclose an individual other than some assertions by census staff.

I had the opportunity to attend one of the 12 regional census press
conferences concerning C2SS and ACS held Nov. 14th and 15th around the
county. Due to the embargoed nature of the data and some of the briefing
materials I waited until today to send this. If you feel this
useful to the list-serve, please post it.
Officials did confirm that "small geographic areas" are indeed census
It will probably take the full four year cycle (2004-2008) to produce
level of geography. I also asked whether or not BG' s or TAZ's would
be a possibility in the future. The response was that the Census Bureau
"most likely" continue to support the planning community with special
tabulations, with the added disclaimer "if confidentiality thresholds
met." Considering the size of the sample and also the size of many
wonder what our chances are.
The press conference seemed to have the tone of a pitch for
funding. If funded ($137 million/year) data for areas less than 20,000
be available until 2008. It seems to me at least that it will be a
to get BG or TAZ level data for 2010. Many major newspapers have
stories on the release of C2SS today. Read a couple to get a feel for
what others think. My comments can be found in the local section of
