RE: [CTPP] 5-year ACS data

by Chris Lukasina

While group quarters may not make up a substantial portion of the population in some areas they do elsewhere, particularly in military or college towns. In some cases this can make up more than 30 percent of the population in the urbanized area and have a large impact on the transportation network. Good, detailed information will be vital to developing good transportation network analysis. From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces@chrispy.net] On Behalf Of Patty Becker Sent: Sunday, March 22, 2009 4:45 PM To: ctpp-news(a)chrispy.net Subject: Re: [CTPP] 5-year ACS data I share Ed's concern over the impact of these rules, although some of them are the result of the switch to the ACS itself. The way the Census samples group quarters for inclusion in the ACS prohibits low level geography reporting for them. We'll be lucky to get anything meaningful by county. However, we will get the SF1 and SF2 tables from the 2010 census itself, so at least we will know where the GQ are, the type, and the population in them, by block. (See Table P37 in the 2000 SF1.) I would submit that, for the most part, people who live in GQ are not very active in terms of using the transportation network, in any event. The basic rule that there will be suppression in tables with more than 100 cells calls for a major rewrite of the table structure itself--for everyone, not just the CTPP community. For example, right now getting the unemployment rate requires you to use a table with more than 100 cells. This needs to be fixed by adding a simple table showing labor force status, maybe by sex, but definitely not by age. This will result in a smaller table and there will be no suppression. I'm sure that many of you can find your favorite examples of this problem. In your responses to the FR notice, please emphasize the need to redo the detailed table structure. That's the only way we're going to get any semblance of the data we need.

I wish I could partake, but this is the day of our annual staff retreat. Would it be okay if I forward this to a couple of colleagues (one in the Seattle Office of Housing and one in Seattle/King County Public Health) who use PUMS data? Also, do you think some kind of reproduction of the webinar/slideshow would be available after April the 16th? -Diana >>> <Elaine.Murakami(a)dot.gov>; 3/18/2009 1:30 PM >>> We are hosting a short session to train users on using the Minnesota Population Center IPUMS . http://usa.ipums.org/usa/ The IPUMS project provides a user-friendly approach to using decennial Census and ACS Public User Microdata Samples (PUMS) including the newest 2005-2007 ACS file and the Census 2000, and many older decennial census files. These microdata samples are a portion of the full individual records and include all the variables. The data are NOT pre-tabulated. If you need a quick tabulation that is not included in a CTPP or a standard Census file like Summary File 3, or the American FactFinder, then using the microdata may be a solution for you. The PUMS are restricted to larger geographic units (Public Use Microdata Area) to protect individual confidentiality. For example, Nathan Erlbaum from New York State recently wanted to know the the impact of group quarters population on bicycle commuting. I ran a table using Census 2000 (includes group quarters) and 2005 ACS (excludes group quarters). Probably I should have compared 2005 ACS to 2006 ACS! By the way, the answer was that group quarters had a large effect on walking for the mode to work, and not much difference on bicycling. You do not need to have statistical software installed on your PC. The SDA program in IPUMS can run simple tabulations, regressions, and logit models. We will learn basic techniques to select rows and columns, filtering (subsetting), re-grouping variable classifications (very important for continuous variables like travel time, departure time, age, income) and even try a simple regression. The on-line software cannot do as sophisticated variable processing as a system like SAS or S+, but it can provide analysts with a quick way to examine basic patterns that can be used to design more sophisticated analyses. DATE: April 16, 2009 Thursday TIME: 1 - 2:30 p.m. Eastern Pre-registration is required: http://www.nhi.fhwa.dot.gov/resources/webconference/web_conf_learner_reg.as… I have reserved 65 slots.
