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. http://ctpp.transportation.org/Pages/webinardirectory.aspx Elaine -----Original Message----- From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces(a)chrispy.net] On Behalf Of Erlbaum, Nathan (DOT) Sent: Friday, March 11, 2011 11:42 AM To: ctpp-news(a)chrispy.net Subject: RE: [CTPP] 2010 Data Release Watch Noted below is a question and a response that appeared on the list serve earlier today and that suggests a solution method to creating data that almost exists but is needed. I am reposting this to the list serve, because I believe that this might be a worthwhile effort for someone who is adept and familiar with IPF to provide a valuable resources to the CTPP community in much the same way the ACS MOE spreadsheets have evolved to explain how to deal with this statistical concept in an easy to use way for the practitioner. Recently there was a post to the listserve by Jonnette Kreideweis about the Census Conference in California and the call for papers. There was also a recent post about the Planning Methods Conference. A spreadsheet that would answer the question posed is potentially a good basis for a paper. Further it helps share skills with the larger practitioner community based upon solutions and techniques that others have implemented. When presented and discussed on a listserve then many more people perhaps those who might never consider this as an option may now have a solution to the very same problem or may move on to adapt the method to other analysis areas. I want to encourage anyone who has the time to give it a try, maybe a student can use this to apply what they have learned, or a modeler can cannibalize something he/she has already used, many may benefit from you efforts. ---------------------------------------------------------- Nathan Erlbaum Associate Transportation Analyst Office of Policy, Planning & Performance New York State Department of Transportation 50 Wolf Road, 6th Floor Albany, New York 12232 (Tel) 518.457.2967 (Fax) 518.457.4944 (E-mail) nerlbaum(a)dot.state.ny.us (Web) www.nysdot.gov >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Marcus Wigan wrote: > ed > > a terribly simple question > > How best to do age group by gender by travel on the CTTP! > best > marc >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 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?

The Atlas highlights the value of the U.S. Census Bureau's American Community Survey as a source of county data, aggregating data from several different federal sources. Through its interactive visual display, the Atlas assembles statistics on four broad categories of socioeconomic factors including demographics, jobs, agriculture indicators, and poverty trends. Users of this information-rich tool have the option to view county-level maps; view the entire country or zoom into specific regions, States, or county areas; view a selected socioeconomic indicator; view a pop-up window showing all the indicators for that county; print a version of the map or save the image in a graphics-file format that may be added to documents or presentations. A few clicks can provide a visual display of trends affecting transportation use, such as the percentage of persons over 65 living alone, retirement destinations projected to expand in the next ten years, and the shape of employment changes throughout the country.

[CTPP] Important TAZ Participant Information - Program Commencement

by Weinberger

Hi All, The TAZ Delineation program is fully deployed. If you are a primary contact you should have received an email with a subject line identical or very similar to: Important TAZ Participant Information - Program Commencement (your area). The email contains your unique set up file and a link to download software and geography. It also instructs you to call 301.763.1099 and ask to speak to a member of the GEO TAZ Team to receive your username and password to access the TAZ MTPS software. If you are a primary contact for TAZ delineation and have not received the email, call 301-763-1099 or email geo.taz.list(a)census.gov for more help. Happy Delineating!

[CTPP] FactFinder 2

by Ed Christopher

I must admit that every time I sit down and try to bolster my skills with the new FactFinder I find myself easily getting distracted and never getting anything accomplished. However, someday I hope to make it through all the tutorials and become as proficient with the new FactFinder as I am with the legacy version. Although it is not quite FactFinder, some colleagues turned me on to an interactive map done by the NY Times where you can begin to pull numbers from the 2010 Census. In less than 3 minutes and without going through any tutorials I was able to view the tract data for my home tract. Here is the link. http://projects.nytimes.com/census/2010/map?ref=nyregion -- Ed Christopher FHWA Resource Center Planning Team 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443 708-283-3534 (V) 708-574-8131 (C)

by Ed Christopher

If you will be creating your Census TAZs and/or TADs attached is the User Guide. It was just released by the Census Bureau and very soon folks will be notified directly by the Bureau that their TAZ materials are available. I would recommend that you take a look at the User Guide before hand to familiarize yourself with the software and most of all IF YOU HAVE TO GET SPECIAL RIGHTS TO LOAD SOFTWARE OF YOUR COMPUTER YOU BEGIN NOW TO TAKE THE NECESSARY STEPS TO OBTAIN ALL APPROVALS. Also to view a demonstration of the software our 2 hour webinar can be viewed from two different locations. http://fhwa.adobeconnect.com/p42996378/ http://ctpp.transportation.org/Pages/default.aspx -- Ed Christopher FHWA Resource Center Planning Team 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443 708-283-3534 (V) 708-574-8131 (C)

RE: [CTPP] RE: how to use Census Redistricting Summary Files in Access

by Patty Becker

We just got Michigan today, and I'm really confused. I downloaded the files from the web site, and I think I understand the 3 different files OK. If I could get them into FoxPro (which I use instead of Access) I'd be fine getting them merged. My problem is that WinZip (version 15.0) won't allow me to rename the .pl to .txt. Tells me that it's a read only file. I can't do anything with mi2010geo.pl -- can't read it in any software. Help! (And why does the bureau do this to us???)
