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.

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.

Re: [CTPP] Distribution Part 2 Data from CTPP 2000

by Peter H. Van Demark

Phil: We are glad to learn that distribution of the final Part 1 data will begin soon, and that distribution of the draft Part 2 data has begun. As a service to TransCAD users, Caliper has been organizing 2000 Census data so that it is easy to access and use. A set of Table Chooser add-ins for TransCAD work with SF 1, SF 3, and CTPP Part 1 data, and the new Version 4.7 of TransCAD includes these Table Choosers as menu commands. A new add-in has been prepared for the CTPP Part 2 data, now that some draft ASCII files are available. We have been processing the data for states and MPOs that send us copies of their ASCII files. We have reformatted these Census data from the many small ASCII files (with all the summary levels) into one file for each summary level (with all the tables). The Table Choosers let users pick which tables they want, from a full list of tables, from tables by organized by subject, and/or from user-defined groups. Users can select the areas for which they want the data, and create a geographic file with both the area boundaries and the demographic data. They can also create just a tabular file, which can be joined to existing geographic files. To make the fields easier to understand and use, metadata are available in balloon help that appears by moving the cursor over the columns headings in a dataview. The metadata were constructed from the documentation for each set of Census data and, for Parts 1 and 2, give the category for each variable, the full table name, and other useful info. When the final ASCII files are released, we will make the CTPP Part 1 and Part 2 Data CDs available. Users in some states, such as Florida, are already working with the draft Part 1 data. As soon as there are ASCII files for CTPP Part 3 data we will process those as well, so we would encourage you to release the ASCII files for all three parts as soon as possible.

Yes, please tell vendors this is not a list for solicitation of information that they have. I'd rather not get E-Mails from vendors, especially ones like this one. -----Original Message----- From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces(a)chrispy.net]On Behalf Of ed christopher Sent: Monday, February 02, 2004 8:51 PM Cc: ctpp-news(a)chrispy.net Subject: Re: [CTPP] Distribution Part 2 Data from CTPP 2000 There are two points I would like add. First, it is my understanding that there are many other vendors who are providing ways to easily interface the CTPP with their products as well. Since I would hope that this listserve does not become simply a haven for product/vendor solicitation I will not mention any other firms by name, which is my second point. "Peter H.
