Hi all,
I am trying to pull together some information about the future 5 year
CTPP release for the small area worker flows... what to expect in terms
of variables, crosstabs, timeline etc. I've checked the primary sites
but maybe I'm missing it. Specifically, does anyone know if the tables
in the 5-year product will be the same as what is offered in the 3 year?
Thanks in advance.

I am not sure if my original post came through and if its a copy i
apologize for reposting (computer issues). Original email below.
Unless I am missing something, Elaine's challenge has not yet been met
or not responded to on this list. Anyway, while trying to IPF a table
in R i ran across this resource
(http://www.demog.berkeley.edu/~eddieh/datafitting.html) that might be
useful to meet Elaine's challenge (there is a bunch of R code that
will help meet the challenge). Elaine has already given Age x Mode,
and Gender x Mode. Link to Age x Gender for workers 16 years and older
[no MOEs included and obtained after raking the marginals of tables
B08101 and B08006] given below so that all the data elements are
available to meet her challenge.
Download Age x Gender for workers 16 years and older from here:

Here is the challenge! I do not know how to do IPF, but I know that many
of you out there can do it!
Attached are: ACS B08101 ; ACS B08006 for Maricopa County Arizona.
You can ignore the MOE cells for this IPF challenge.
Also attached is a 3-way tabulation using IPUMS for Maricopa County AZ.
All are using 2009 ACS.
You will note that carpool is not broken out, as the question is really
in 2 parts (what mode, and then how many people), so this table could be
re-done by creating a carpool variable, if you wanted.
We have an archived webinar on using IPUMS, if you are interested in
making your own tabs using ACS PUMS.

Ed Christopher's response:
Unfortunately, there is no clean way to get Age by Gender by Mode (Means
of travel), that I know about, directly out of the current 3-year CTPP
data product nor the Standard Census ACS products for that matter.
However, there are some options that will get you close but they will
take a little work.
Option 1. In CTPP take table 12201 ( Age by Mode to work) and table
11203 (Age by Sex/gender)and run an IPF (Iterative Proportional
Fitting-fratar) routine between the two tables to get what you want. At
least I think it will work.
Option 2. Do the same with standard ACS product tables B08006 (Sex by
Mode) and B08101 (Mode by Age). If you go this route I think these
tables may even exist in the 5-year ACS so you could do it at smaller
than Places over 20K population geography.
Option 3. Just make your table using the PUMS data but you would be
limited to geographical areas of over 100K people.
Over the years we has suggested that people use an IPF routine to make
tables that might not exist in the various data products. I would be
interested in hearing if anyone has actually done it. Have you?
Hi Everyone --
I attended a Federal Data Users Workshop at the Census Bureau last week. Nancy Torrieri (CB) announced this new ArcGIS extension at the meeting. I haven't had time to look at it, so I hope that some of you will take the time to do so, and report back to the listserv with your results!
This is an extension that works with ArcGIS 9.3 or 10.0 Please visit the George Mason University website at:
http://gesg.gmu.edu/census
I LOVE the listserv! I am so glad that Ed Christopher set it up so many years ago when he chaired the TRB subcommittee on Census data. AND, I love how everyone helps each other out!
The reason that I was at the Census Bureau is that they are conducting an ACS Program Review that they expect to run for 12-18 months. The workshop for people from Federal agencies was one of the 8 parts of the program review. They are also planning for ways for non-federal data users to be part of this review, including a CNSTAT workshop to be held in Fall 2011 (don't have a date), and other outreach from the ACS Communications team.
James B. Treat, the Chief of the ACS Office, said they MUST look at reducing the size of the ACS products and need data users to convey their preferences and understand that trade-offs must be made. They need to know if the 3-year products are used, or people mostly want the 5-year products, and which geographic summary levels are needed. For example: how much tabulation for tracts split by place? vs. whole tracts.
And finally, in case you had not heard, the Census Bureau announced a few weeks ago that they will be closing 6 of the 12 regional offices by the end of 2012.

On Thursday, July 7 , the U.S. Census Bureau will release a 2010 Census
Summary File 1 Microsoft Access table shell. The table shell will
provide an easier way to access Summary File 1 information from the
Census Bureau's FTP site
http://www2.census.gov/census_2010/04-Summary_File_1/. Instructions for
how to use the shell and work with the information will also be included
in the .zip file.
Some of the tables in Summary File 1 of interest to transportation
planners include:
P12 Sex by Age (23 age categories)
P14 Sex by Age (Single years 0-19)
P19 Household size and type by presence of children (19 cells)
P28 Household type and Household size (16 cells)
P42 Group Quarters by GQ Type (10 cells)
H3 Housing Units
H12 Average Household Size by Housing Tenure (own/rent)
For more information on which states have been released, please see:

I was able to download a table containing county-level population statistics. But the downloaded file contained only the data for the particular county that was displayed in the results tab. The file did not contain data for the other 87 counties that I had also selected.

Has anyone successfully downloaded a table in AFF2 in the last 24 hours or
so? I can pull up the data I need but when I try to download it I either get
a broken zip file or an error. My computer environment has changed so I am
trying to figure out if the problem is the website or some setting on my
computer.

If someone has Access experience can help, I would love to know how to
delete all the HI records from three tables I imported for testing
purposes of the great Access instructions.
I need to get the data out of there before KY's comes out and I don't
use Access much.
Thanks

Hi I did the MS ACCESS Directions and it worked and was easy.
I did the HI example (except I chose a different table than the example)
and I guess with interruptions it still was fairly brief; e.g. less than
half hour.

Would anyone like to volunteer to test out these directions and then
report back to the CTPP listserv on how well it worked?

thSummaryFile1.pdf
Sometimes when I send an email, the link gets broken. The full link
ends in "....pdf"
In the meantime, I am testing out the data access system at the Missouri
data extractor (Dexter/uexplore) to look at Summary File 1. It is
pretty easy, so far.
http://mcdc.missouri.edu/cgi-bin/uexplore?/pub/data/sf12010
on this page, select the FIRST LINE "Datasets.html" then I selected
Colorado.
I chose counties in Denver 08031 using the FILTER (first set of
boxes) and selected "tracts" and then I selected Table H 12 and got a
comma-delimited file, which I read into excel. You have to select BOTH
the geography fields in the LEFT box as well as the table (variable)
fields in the RIGHT box. If you forget to select the geography fields,
you will get the table variables without any corresponding geography,
which is not very useful. Ask me how I know. J
Finally, I thought that when the Census released the Summary File 1
files on the ftp site that it meant the data would also be in AFF2, but
apparently this is not true. There are "quick tables" in AFF2, and
these may satisfy your needs, but it is not the full set.
