[CTPP] aggregated MOE for 6 counties

by mkaminowitz＠baltometro.org

Hello, I need to get a regional estimate and MOE composed of 6 counties. I know the rule of thumb is that aggregating MOE's doesn't work well for more than 4 units. Does anyone know is using 6 would cause the MOE to be inaccurate? Mara Kaminowitz GIS Analyst .........................................................................

[CTPP] CB ACS Program review: CNSTAT looking for non-federal ACS data users

by Elaine.Murakami＠dot.gov

This request was in the Association of Public Data Users (APDU) email list: American Community Survey Workshop The Committee on National Statistics, with sponsorship from the Census Bureau, is convening a Workshop on the Benefits (and Burdens) of the American Community Survey, ideally to occur in mid-June. This workshop is intended to showcase the nonfederal uses of the ACS, while at the same time taking stock of the burdens that it imposes on the public, and to suggest priorities as ACS data users transition from the products of a long-form sample to the range of ACS products. The steering committee is engaging in a broad scan of users (and potential users) of the ACS, to help shape a useful and informative agenda. At this stage, the steering committee would greatly appreciate it if you could send a brief email, indicating whether: * you are an ACS user, whether of 1-, 3-, or 5-year estimates, or particularly of the PUMS or summary files; * you are doing or have done work using ACS data that might be appropriate to showcase at the workshop; and * you know of people doing applied work with the ACS. Please send responses to Ken Hodges<mailto:ken.hodges(a)nielsen.com>. ------------------ THEY ARE LOOKING FOR POTENTIAL PARTICIPANTS. I am thinking that based on the October TRB Census conference, some of the people who might want to contact Ken Hodges might be: Mara Kaminowitz, Baltimore Metro Council re: uses for environmental justice analysis and TIP evaluation Behruz Paschai et al from NCTCOG re: problems with average hhld size and use in population forecasting Demetri Messen, HGAC re: using ACS PUMS for demographic and economic forecasting Guy Rousseau, ARC re: using ACS in population synthesis for activity-based models Someone representing using CTPP with or without LODES (LEHD) for transit New Starts In addition to this planned workshop, the Census Bureau also sent out an email request for feedback on the ACS. The CTPP Oversight Board is working on a coordinated response. For more information about that, please contact Penelope Weinberger at AASHTO: pweinberger(a)aashto.org<mailto:pweinberger(a)aashto.org> While I haven't seen a recent draft, I know that some of the topics that have been discussed include: improving data access (i.e. problems with AFF), adding a geographic unit like a TAD for 3-year tabulation for complete geographic coverage (no swiss-cheese), and adding a simple home-to-work tabulation of worker counts to the 3-year (PUMA or TAD) and 5-year tabulation (tract).

[CTPP] 2000 Census Traffic Analysis Zones

by Messen

Would anybody know what the deal was with the 2000 Census Traffic Analysis Zones? I am working with CTPP 2000 Table 3 data. To do some spatial analysis, I turned to census boundary files for traffic analysis zones (http://www.census.gov/geo/www/cob/bdy_files.html). I quickly realized that 63 out 2639 zones for the Houston region are represented by 2+ non-adjacent polygons. Does this happen in other regions as well? Was this delineation done purposefully or perhaps these are simply errors stemming from TIGERLine 2000? Any input will be much appreciated. Thank you. Dmitry Messen H-GAC dmessen(a)h-gac.com

Re: [CTPP] Elaine's notes from the January conference: Federal Committee on Statistical Methodology

by Elaine.Murakami＠dot.gov

The people from Stats Netherlands said they got the data from the telecommunications provider, it is NOT a sample, for "all" data for a 2 week period, but they did not discuss HOW they negotiated the use of the dataset. From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces(a)chrispy.net] On Behalf Of Krishnan Viswanathan Sent: Friday, February 17, 2012 12:21 PM To: ctpp-news(a)chrispy.net Subject: Re: [CTPP] Elaine's notes from the January conference: Federal Committee on Statistical Methodology Elaine Thanks for sharing this. One question - How did the Stats Netherlands people get access to the data from the cellphone providers? Maybe there are some lessons there about structuring the request and alleviating public fears that can be useful to data collection efforts here. Or did they select their sample and then approached the providers with explicit permission from this sample of the cellphone customers. In general, my impression is that overseas it is a bit easier for agencies to obtain data than here.

Re: [CTPP] Census/ACS data downloads

by Jonathan Lupton

Ms. Gemignani: Thanks for the tips with AFF2. I tried, but failed. I'll share this with the list serve because it may be instructive to others. I'm probably missing something simple, but this may help reveal the (multiple) fallacies of AFF2. After selecting the county geography, I did as you said in the message below: I typed in "labor force age sex." This was great. I got a long list of 2010 ACS tables, but at least they resembled what I'm looking for. Then I typed in "2000 SF3" and got: "No tables, files or documents were found that match . blah blah." What am I doing wrong here? When I try scrolling through the multiple pages of results, I go through two pages of 2010 ACS. Then I run into 2009 ACS. How many dozens of pages must I scroll through to get Census 2000? I also can't help but use this as commentary on AFF2. I'm a data user with years of experience and training. If I can't easily find what I need, what hope does the general public have? Very little of Census 2000 is available in printed form. Will it become the "dark age" Census, that nobody can get to? Again, thanks for taking the time. I would like nothing more than to be able to make full use of AFF2. Jonathan Lupton From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces(a)chrispy.net] On Behalf Of Gemignani, Nancy Sent: Friday, February 17, 2012 1:22 PM To: ctpp-news(a)chrispy.net Subject: Re: [CTPP] Census/ACS data downloads Jonathan, Sounds like you have found the table and have a simple geography (counties). I would have downloaded the table as a csv file and open it in excel. Manipulate it there to remove the variables you don't want and calc the LFPR. Are you looking for something that will extract the exact cells (total pop and in LF) you need? You could use the "modify table" function in AFF but I agree - at this time that is kinda clunky and slow - because you can only make one change at a time. But to me AFF to Excel is much faster than DataFerrett for pulling a table for multiple geographies. I guess it is just what you are comfortable with. Using the info, Mara Kaminowitz from Baltimore sent out earlier this month, once you know the specific table you want, you can construct a direct link like this one which will pull table PCT 35 from 2000 SF3 for Arkansas statewide and all its counties: http://factfinder2.census.gov/bkmk/table/1.0/en/DEC/00_SF3/PCT035/0400000US0 5.05000|0400000US05 BTW - this table is also available by race as table PCT079 in SF4. Its link to the data for Hispanics would look like this: http://factfinder2.census.gov/bkmk/table/1.0/en/DEC/00_SF4/PCT079/0400000US0 5.05000|0400000US05/popgroup~400 I have found that that the text search feature has greatly improved in AFF2. I typed "labor force age sex" (219 results) then selected 2000 SF3 (1 result). Now pick your geography. A handful of clicks got me to the data. If you are not familiar with the tables in the census data files, the search is actually improving into a useful tool.

I must reluctantly confess that I am still struggling, and would like to know how other members on the CTPP list serve are faring. Here are my conclusions at the moment: 1. AFF2 is useful for obtaining pre-organized data profiles (despite its clunky and counter-intuitive interface), but in my experience it's still hard - even with the benefit of some training - to really drill down into the kind of esoteric data I sometimes need. 2. Data Ferret is great for batches, like downloading a fair amount of data for multiple geographies (like all BGs in a county, etc.) but I'm having a hard time drilling down to the highly specific items I need. My latest troubles involve trying to get employment/labor force participation by age and sex for counties and/or my metro area from SF-3 in Census 2000. I have been able, with the help of Data Ferret, to obtain the table numbers (PCT 3500-PCT 3518), but Data Ferret can't seem to give me the figures I need in a single download, and multiple downloads are proving error-prone and troublesome. Searching the table numbers in AFF2 yields the typically useless results. My search of the Missouri State Data Center site, while much appreciated, hasn't yielded the results I need. My own State Data Center (Arkansas) has some useful profiles, but again not as specific as I need. Does anyone else have tips? I feel like I could use further webinars on Data Ferret or - just possibly - AFF2, although I'm deeply suspicious of trying to make anything useful out of AFF2, since results so far have been disappointing. The seminar on Data Ferret back in December was helpful, but didn't have a lot of in-depth training on large downloads, highly specific data needs, etc. I'm deep in 'flyover country,' and hence there's a lack of training and information exchange available. Surely others face the same issues. Does anyone else want more web-based training, too? Jonathan Lupton AICP Research Planner Metroplan Little Rock, Arkansas

Re: [CTPP] Census/ACS data downloads

by Krishnan Viswanathan

Jonathan Here is some Perl code which you might find useful to extract the data you want. This code is written to obtain specific ACS data tables from tracts in multiple counties and put it all in a single file. The README tab describes the process in detail. You can modify it to fit your needs. Hope it helps.
