Don, I think the file is laid out in the exact same way as the PL-94-171 files. The software they are talking about is probably "allocate" and may be found on the PL-94-171 disk, so you can order one from the Census Bureau State Data Ce nter closest to you. The other way to do this is to follow my procedure posted a while ago on PL fi les. http://www.fhwa.dot.gov/planning/census/pl2gis.htm Thanks Nanda Srinivasan Here's a possibility: Fromust a quick look at the file(s) structure, what you get when the files a re unzipped is something very similar to the SF1, 100% counts (someone please correct me if I'm off-the-wall, here). Way back when the Redistricting files w ere released, someone on this listserve was kind enough to share his (very use r-friendly) SAS program. That program can be altered for SF1, and with cut-and -paste, and a little tweaking, I believe the same program can be used for the adjusted counts. Haven't tried it yet, though. Good luck! Liz Hartmann Research Analysis Specialist Minnesota Department of Transportation Office of Investment Management Pardon my ignorance, but perhaps someone would be kind enough to suggest how I might be able to at least view the data from the unzipped files. The technical documentation referrs to a simple software program on the CD-ROM disk which allows the data to be viewed--similar to what FactFinder does. Thanks.
