[CTPP] PUMS on DVD, MS-Access tutorial

by Chuck Purvis

There are two newsworthy items related to the Census Public Use Microdata Data. 1. The first is the recent release of the PUMS DVD. This DVD includes the entire U.S. dataset for the 1-percent and 5-percent PUMS, and includes the Beyond 20/20 software to produce user-defined cross-tabulations of PUMS data. This software is VERY fast and is excellent for developing basic two-way, three-way, four-way, n-way cross-tabulations of PUMS. (For example, to produce a California tabulation of persons by PUMA of residence by tenure by vehicles available by means of transportation to work took just a few seconds to produce this four-way table....Hours to analyze, just seconds to create!) The DVD contains about 3.9 gigabytes of data and software, including the national set of raw ASCII record data. You can use the Beyond 20/20 to create your own tabulations and export into various database formats, like csv, txt, xls, dbf, wk1, wk2, etc. The DVD costs $70.00, and is available from the Census Bureau at: http://www.census.gov/mp/www/Tempcat/C2KPUMS.html 2. There was a message on the Investigative Reporters & Editors' Census listserv, from Professor Steve Doig of Arizona State University, on some Microsoft Access code that Mr. Dick O'Reilly of the Los Angeles Times is making available. From Prof. Doig: "It's been a while since I put anything new on my "Reporting Census 2000" site. But Dick O'Reilly of the LA Times has gifted us with a PUMS tutorial, complete with import specs and sample data and queries, that he put together for those unfamiliar with the oddities of PUMS." Go to this page, and follow the navigation bar to What's New: http://cronkite.pp.asu.edu/census/ This is an excellent "how-to" Census site, and has some great information for non-journalists, as well. The MS-Access "PUMS Tutorial" was uploaded 2/10/04. (Please don't ask me about MS-Access or how this works. I have Access on my machine, but I use SAS as my workhorse software to process PUMS data....) Hope this helps, Chuck Purvis, MTC ************************************************************** Charles L.

RE: [CTPP] Average Miles to Work

by Srinivasan

I am pretty sure there is no mention of average trip length in the Journey to Work Trends Report. The average one-way commute trip is 12.2 miles according to the 2001 National Household Travel Survey. Thanks Nanda Srinivasan -----Original Message----- From: Shea, Sam J.

RE: [CTPP] Average Miles to Work

by Murakami

I used the NHTS on-line table generator to run these numbers for you. The trip purpose (1990 NPTS definition of TO AND FROM work) was used and applied to the 2001 NHTS. This is a different definition from decennial Census journey-TO-work. So, I also ran the travel time, with the 2001 results nationwide being 23.5 minutes. From decennial census, we get 25.5 minutes for journey-to-work in 2000. You can use the NHTS on-line table generator to examine distributions of trip lengths and trip durations by trip purpose. http://nhts.ornl.gov/2001/index.shtml Elaine Murakami, FHWA Office of Planning; 206-220-4460 2001 NHTS Average Person Trip Length (miles, Travel Day) Where worker = '1' (Continued) TD Person Trip Length Sample Size Mean 1990 NPTS trip purpose 35,658 12.21 To/From Work Work-Related Business 6,959 30.24 Shopping 25,449 7.29 Other Family/Personal Business 32,559 7.46 School/Church 6,600 7.80 Medical/Dentral 2,338 11.04 Vacation 738 45.12 Visit Friends/Relatives 7,942 18.15 Other Social/Recreational 22,250 9.35 Other 746 19.47 N/A 460 89.97 Refused 9 6.14 All 141,708 11.25 Average Person Trip Duration (minutes, Travel Day) Where worker = '1' (Continued) TD Person Trip Duration Sample Size Mean 1990 NPTS trip purpose 35,638 23.50 To/From Work Work-Related Business 6,951 33.46 Shopping 25,337 15.16 Other Family/Personal Business 32,337 15.87 School/Church 6,612 17.10 Medical/Dentral 2,342 21.29 Vacation 736 61.88 Visit Friends/Relatives 7,867 27.11 Other Social/Recreational 22,127 20.84 Other 747 34.76 N/A 479 49.22 Refused 9 14.61 All 141,182 20.58 -----Original Message----- From: Estersohn Dan [mailto:Dan.Estersohn(a)arbitron.com] Sent: Mon 2/9/2004 5:06 PM To: ctpp-news(a)chrispy.net Cc: Subject: [CTPP] Average Miles to Work We are working on a project that requires a U.S.-level average miles to work number.

[CTPP] Distribution of CTPP Part 2

by ed christopher

Very late last week week I picked up this email form Phil Salopek regarding the distribution of Part 2. Things are starting to roll. -----Original Message----- From: phillip.a.salopek(a)census.gov We did not get as many states shipped this week as we had hoped, because people in the office doing the duplication were off due to the weather and our mail service was suspended because of the ricin incident. But as of today we've sent 9 CDs with 22 states. We could very possibly finish the distribution next week. Here's what has gone out so far. January 29, 2004 CA and NV IN and MI NY and NJ OH and KY January 30, 2004 GA, SC and TN ID, OR, UT and WA February 5, 2004 IL and IA FL DC, MD, NC and VA

[CTPP] 1970 census transportation mode to work data

by William Schaefer

The 1970 Census used "private auto-driver" and "private auto-passenger" as transportation modes to work versus "drive alone" and "carpool." Does anyone know whether private auto-driver includes only SOVs? The term implies that it could include those who drive, but were part of a carpool. The Census book I have does not define the terms. Thank you. Bill Schaefer Madison (WI) Area MPO

Re: [CTPP] 1970 census transportation mode to work data

by celia.g.boertlein＠census.gov

The 1970 Census Questionnaire Reference Book and the Instructions to Respondents both include the following guidance-- "...Private auto" -- Mark "Driver..." if he drove on the last day he worked at the address given in 29c, mark "Passenger..." if he did not drive. (Item 29c that is referenced is the geographical location of the person's place of work.) -- Celia G. Boertlein Journey-to-Work and Migration Statistics Branch Population Division U.S. Bureau of the Census Washington, DC 20233-8800 phone: (301)763-2454 fax: (301)457-2481 email: Celia.G.Boertlein(a)Census.GOV Patty Becker <pbecker(a)umich.edu To: "William Schaefer" <wschaefer(a)cityofmadison.com>, ctpp-news(a)chrispy.net > cc: Sent by: Subject: Re: [CTPP] 1970 census transportation mode to work data ctpp-news-bounces@ chrispy.net 02/05/2004 05:55 PM I am looking at a reproduction of the 1970 questionnaire. It's item 29d, in the 15 percent sample only. It reads: How did he [note the old sexism] get to work last week? Fill one circle for chief means used on the last day he worked at the address given in 29c. Driver, private auto Passenger, private auto Bus or streetcar Subway or elevated Railroad Taxicab Walked only Worked at home Other means (specify)__________________ I would be willing to bet that all SOV respondents are in the first category. In the rare instance of a carpool, a respondent would put him/herself in the first category if they drove on the last day, and in the second category if they did not. Remember, this was before the first big energy crisis and carpooling wasn't very common back then. On the other hand, public transit was used a lot more than it is now! Sorry--I had a birthday yesterday and I am reminded once again that I was indeed mostly a SOV driver in 1970.
