RE: [CTPP] Census 1980 Urbanized Areas - Maps

by Jim Hubbell

I recently looked into this, and learned that the 1980 UZA boundaries were never digitized by the Census. You might check with other agencies in your region to see if it was done independently.

RE: [CTPP] Census 1980 Urbanized Areas - Maps

by Srinivasan, Nanda <FHWA>

I know that the USGS made an effort to work on Urban areas for 1980, but these may have been different from Census urbanized areas. I think the USGS data is documented in the national atlas for geospatial data. The website is: http://nationalatlas.gov/natlas/NewLayerList.asp Thanks Nanda Srinivasan >>> JHUBBELL(a)MARC.ORG 11/21/02 09:58AM >>> I recently looked into this, and learned that the 1980 UZA boundaries were never digitized by the Census.

Update on the NHTS

by Nancy Mcguckin

Update on the Status of the 2001 National Household Travel Survey The 2001 National Household Travel Survey (NHTS) is the most current inventory of the nation's daily and long-distance travel. This survey combined the NPTS, a data series collected since 1969 by the FHWA and focused on daily travel, and the ATS (American Travel Survey) which collects information on longer-distance trips. The preliminary data is scheduled for release in January 2003. A workshop and roll-out of the NHTS 2001 is being planned for Sunday, January 12th (1:30-5:00 PM) at the annual meeting of the Transportation Research Board. The data will also be available on the web, and updated according to the following schedule. Schedule of Data Release: January 2003 - Preliminary data released (national sample with daily trips only). This preliminary release will include weighted data representing the nation's daily travel. The data will be available on the NPTS data series website with a User's Guide and the on-line analysis tool at: www-cta.ornl.gov/npts Spring 2003 - Second release (national sample with daily and long-distance trips). The second release is the full continuum of travel for the nation, including daily and longer-distance (over 50 miles from home) travel. The reporting period for long distance travel was a 28-day recall period with the travel day as the last day. Summer 2003 * The final, full data set is released for public use. The final release includes all national data, daily and long-distance travel, plus the additional samples from the nine add-on areas correctly weighted and edited to represent the nation's travel. Published results begin to be released with the final dataset. Hope to see you at TRB! Nancy McGuckin Travel Behavior Analyst (202) 366-8750 Nancy.McGuckin(a)fhwa.dot.gov

PUMS release dates

Place of Residence Profile Sheets from Census Transportation Planning Package

by phillip.a.salopek＠census.gov

CTPP PROFILES (November 12, 2002) The first data product of the Census Transportation Planning Package 2000 (CTPP2000) is now available. The Census Bureau has prepared profile sheets for states and counties, which are posted on the American Association of State Highway and Transportation Officials (AASHTO) web page at http://www.transportation.org/ctpp in both html format and pdf format. The html format can be read easily into a spreadsheet while the pdf format can be printed easily. One convenience of these profile sheets is that they include data from both 1990 and 2000 for some basic characteristics such as household size, vehicle availability, means of transportation to work, and travel time to work. Notes about the data in the CTPP profiles: 1. GEOGRAPHIC LEVEL REPORTED: Data are limited in most cases to state and county totals. In six states, (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont) data for minor civil divisions (MCD) are also included. 2. DATA ROUNDING: In CTPP 2000 and other special tabulations from Census 2000, figures that do not duplicate data released in standard census products are being rounded. Therefore, certain tables in the CTPP profile sheets contain rounded numbers. In these tables values from 1 through 7 have been rounded to 4, and values greater than or equal to 8 have been rounded to the nearest multiple of 5. 3. DATA SOURCE IS DECENNIAL CENSUS LONG FORM: All of the data in the CTPP Profile are from the "long form." The data will not match the short form (100% count) data exactly. 4. MICROSOFT EXCEL 97 PROBLEM: There is a display problem when the CTPP2000 profiles in html format are opened in Microsoft Excel 97. The problem is that the second column (column B) of the spreadsheet is hidden from view. To display column B, right-click the mouse over either the column A or column C header, and choose Unhide from the pop-up menu. This problem appears to be corrected in later versions of Microsoft Excel. 5. MEANS OF TRANSPORTATION TO WORK: Public transportation includes bus or trolley bus, streetcar or trolley car, subway or elevated, railroad, ferryboat, and taxicab. In subsequent CTPP2000 tabulations, taxicab will generally be included in the "other means" category. However, in the CTPP profiles taxicab has been included in public transportation, similar to aggregations used in the Census 2000 demographic profiles. 6. TRAVEL TIME TO WORK: In the 1990 Census (including the CTPP data), the maximum travel time assigned to any worker was 99 minutes. Workers who reported travel times of 100 minutes or more were top-coded to 99 minutes in 1990. The maximum travel time was increased to 200 minutes for Census 2000, thus the 2000 data are more accurate because they include the actual value for these long trips. The impact of this coding change is that increases in travel time between 1990 and 2000 are somewhat over-stated. At the national level, the Census Bureau estimates that about 29% (0.9 minutes) of the 3.1-minute increase in average travel time between 1990 and 2000 is attributable to the coding change. 7. HOUSEHOLD INCOME IN 1999: In a small number of cases, the mean household income and median household income figures shown in the CTPP2000 profiles differ from those published in other Census 2000 products. These differences of one dollar are the result of software rounding differences and hardware numeric precision differences between the two platforms used to create the products. 8. VEHICLES AVAILABLE: The data in CTPP2000 on vehicles available are tabulated for households. This is different than in standard census products, where data on vehicles available are tabulated for housing units. Although the estimates are usually quite close, the number of housing units is not always equal to the number of households, because the Census Bureau calculates weights differently for housing units and households. Therefore, the distribution of vehicles available shown in CTPP2000 will not exactly match the distribution (or mean number of vehicles per household) presented in standard census products from either 1990 or 2000. For additional information about CTPP2000 products, please see http://www.fhwa.dot.gov/ctpp/content.htm or http://www.trbcensus.com

Release of 2001 Supplementary Survey Data

by Chuck Purvis

TO: CTPP-News In today's "Census Product Update" (11-7-02) is the news item: Census Bureau Director to Brief Media on Release of Major Survey. (Released November 4, 2002) <http://www.census.gov/Press-Release/www/2002/cb02cr21.html> The Census Bureau director is in Austin, this morning, to talk about the C2SS and the SS01 (Census 2000 Supplementary Survey and the 2001 Supplementary Survey). Folks may be interested in the "Press Kit" for this news conference, and Director Kincannon's slides. His first slide is about changes in mean travel time to work for the US, Texas, the Austin, Dallas, Forth Worth, Houston and the San Antonio MSAs. http://www.census.gov/Press-Release/www/2002/presskit_SS01.html So, what this means is that the 2001 Supplementary Survey "Wave 1" data is now available, generally for very large areas. I'm starting to check out the data for my Big Counties and Metro Areas, and I recommend starting at the 2000-01 "changes" site, at: http://www.census.gov/acs/www/Products/Profiles/Chg/2001/SS01/index.htm In addition to the SS01 data, the Census Products news release mentions the first release of CTPP data: U.S. Census Bureau Announces Availability of First Census Transportation Planning Package (CTPP 2000) Data. (Released October 31, 2002) <http://transportation.org/ctpp/home/default.htm> Hope this is of interest. Chuck Purvis, MTC
