News from the Census Bureau on the 1-percent PUMS file. From their 4/11/03 Products Update listserv e-mail: "HOT TIP I am eagerly awaiting the Census 2000 microdata. What can you tell me about it? Starting later this month the Census Bureau will begin releasing state files with 1 percent of the microdata records for households that answered a long form (the sample questionnaire). Microdata records show the actual responses made by households -- less any identifying information that would violate the confidentiality of the respondent's answers. These files allow users to create their own tabulations. The files will be available online in ASCII via FTP. Once all states are released, we will release the full 1-percent microdata on a CD-ROM to be sold for $50 by the Customer Services Center. The disc will come with Beyond 20/20 software facilitating the use of the disc. Later in the year the Census Bureau will release a 5-percent microdata file, again on a flow basis online in ASCII via FTP. Once all states are released, we will release both the 1-percent and the 5-percent microdata files on one DVD to be sold by the Customer Services Center. For more details on these files and their geographic identifiers, go to < http://www.census.gov/population/www/cen2000/pums.html>gt;.
