Will the data fields for Stf 1, data by block level, be the same as they were in the 1990 census? Or can anyone tell me where to find out. I have looked through the Census web site.

Re: Update on the Status of the NPTS and the ATS

by Nancy Mcguckin

The National Household Travel Survey (the NPTS/ATS) is starting up in early March, and will continue in the field for one calendar year. The national sample is 25,000 households, add-on areas may add another 20,000 samples. The questionnaire combining the two surveys has been smoothed, and a few interesting data items have been added. We are obtaining information on work at home, internet availability and use, immigrant status, travel disability, and greater trip purpose detail. The questionnaire will be available on the website within the next week or two. The website address for the combined survey is: www.bts.gov/nhts Thanks to everybody who let your needs for this data be known. We have really been heartened by the amount of interest and support for the surveys.

Re: [CTPP] Stp 1 - Block level data

by Srinivasan, Nanda <FHWA>

There are a few changes in Summary File 1 specifications. You can access the SF1 specifications (current as of June 2000) from the State Data Center Clearinghouse website at: http://www.sdcbidc.iupui.edu/2k/products/products.html The Census Bureau can correct me if there have been any changes in SF1 plans since June 2000. Thank you Nanda Srinivasan >>> jhoek(a)gvmc.org 01/15/01 10:08AM >>> Will the data fields for Stf 1, data by block level, be the same as they were in the 1990 census?

They are back...

by ed christopher

Those Census 2000 'news alerts' that kept us informed of the Congressional activities surrounding the census are back. For more than four years the Census 2000 Initiative, a coalition of civil rights, women's rights, labor and public interest organizations supporting scientific sampling for Census 2000, distributed the News Alerts detailing the planning and then the taking of the most recent decennial census. Previous issues of the News Alerts, and fact sheets on all aspects of Census 2000, are available at the Initiative's web site at http://www.census2000.org. I was on the mailing list for the 'news alerts' and the last one was published in September 2000. Today I just receive a new 'news alert' and a notice that the Census 2000 Initiative Group would continue publishing them throughout 2001. They sent it along as a Word file which i have attached. Enjoy

TIGER 2000 redistricting release

by Chuck Purvis (MTC)

To: CTPP-News >From the Census Bureau's 12/29/00 "Tipsheet": "Redistricting Census 2000 TIGER/Line Files -- The Redistricting Census 2000 TIGER/Line files, intended to support the needs of state redistricting efforts, are being released by state. Files for all 50 states, the District of Columbia and Puerto Rico will be available over the next several weeks. These files do not contain Census 2000 population data." The Census Bureau is releasing the new Census 2000 TIGER/line files, for redistricting purposes. As of this morning (1/2/01), data for seven states has been released (IN, LA, NJ, NY, OH, TX, VA). http://www.census.gov/geo/www/tiger/index.html I've reviewed the metadata and caveats regarding these "Redistricting TIGER Files" and have some questions. Apparently these are the "semi-final" TIGER 2000 files, and don't include the final address ranges or the ZCTAs (zip code areas.), but: 1. Do these TIGER files include the "final" Census Tracts, Block Groups, Blocks that will be used in PL 94-171, SF-1, etc, ? 2. Do these TIGER files include the "final" validated travel analysis zones that we've been working on? 3. We're working in ArcView 3.x at my agency. There is a shareware Arcview extension "TIGER Reader" (dated 12/7/98) by www.mapclick.com, that I downloaded from ESRI's site. I was able to import the TIGER 2000 data using MapClick's extension for some county in Louisiana, but I'm not sure that this extension is working perfectly with TIGER 2000 (and I haven't been able to access mapclick's web site....) So, are there any users out there who know about other more recent ArcView extensions to read in raw TIGER 2000 files, or can provide any other advice? 4. Are there any other GIS and Census related listservs (internet mailing lists) that are relevant to this discussion? 5. *When* do we know when the TIGER files (and PL 94-171 files) for our state are ready? Do I have to visit the Census Bureau's web site once in a while to check out what's new? What about the Census Bureau instituting some sort of "user notification system" that notifies users when their relevant data files are now available (i.e., data files released by state.) Or does this system exist already? Thanks in advance & Happy New Years to All!

RE: [CTPP] TIGER 2000 redistricting release

by Srinivasan, Nanda <FHWA>

To add to Bob's e-mail Chuck asked: 4. Are there any other GIS and Census related listservs (internet mailing lists) that are relevant to this discussion? THE CENSUS BUREAU'S STAFF TAKE QUESTIONS ON TIGER BY E-MAIL AT tiger(a)census.gov. They are very responsive, and I have found their answers informative. Several listserves contain some questions on TIGER from time to time, but I don't know if anyone solely deals with TIGER/Line. Thank you Bob! Nanda Srinivasan >>> rlamacchia(a)geo.census.gov 01/02/01 01:04PM >>> See the answers that I have for Chuck's message below.

Apparently these are the "semi-final" TIGER 2000 files, and don't include the final address ranges or the ZCTAs (zip code areas.), but: THIS IS MISLEADING. THESE ARE FINAL FILES. THE ONLY ITEM MISSING IS THE ZCTAS (YET TO BE DELINEATED). IN ADDITION, THERE WILL BE SOME MORE TWEAKING OF THE ADDRESS RANGES WHICH SHOULD IMPROVE GEOCODING IN A FEW AREAS WHERE THERE IS NO COVERAGE IN THE REDISTRICTING CENSUS 2000 TIGER/LINE FILES. THIS ADDITIONAL TWEAKING IS BASED UPON THE FINAL MASTER ADDRESS FILE (THE LAST TWEAKING WAS DONE IN THE SUMMER OF 2000 BASED UPON THE MASTER ADDRESS FILE AT THAT TIME). SUBSEQUENT VERSIONS OF TIGER/LINE, AS ALWAYS, WILL HAVE ADDITIONAL ADDRESS RANGE TWEAKING. 1. Do these TIGER files include the "final" Census Tracts, Block Groups, Blocks that will be used in PL 94-171, SF-1, etc, ? YES. 2. Do these TIGER files include the "final" validated travel analysis zones that we've been working on? YES 3. We're working in ArcView 3.x at my agency.

So, are there any users out there who know about other more recent ArcView extensions to read in raw TIGER 2000 files, or can provide any other advice? I WOULD NOT EXPECT THE EXTENSION TO WORK CORRECTLY. WE USE GIS TOOLS TO MAKE SHAPE FILES, AND THE LATEST VERSION WORKS. 4.
