Other sources of information about SIPP include the SIPP Quality Profile, User Notes, and SIPP working papers. The SIPP Web site includes an extensive bibliography that provides references to SIPP-related research and documentation, data dictionaries, variable metadata documenting all information relevant to variables that appear on the public use microdata files, and a computer- based tutorial that introduces users to methods and concepts needed to use SIPP data.
The SIPP Quality Profile documents data quality issues related to SIPP. It summarizes what is known about the sources and magnitude of errors in estimates based on SIPP. The SIPP Quality Profile covers both sampling and nonsampling error, with an emphasis on nonsampling error. There have been three editions of the SIPP Quality Profile. The third edition, by Kalton, Winglee, & Jabine (U.S. Census Bureau, 1998a), updates the two previous editions, by King, Petroni, & Singh (U.S. Census Bureau, 1987) and Jabine, King, & Petroni (U.S. Census Bureau, 1990). The third edition of the SIPP Quality Profile is available on-line on the SIPP Web site.
The SIPP User Notes, issued periodically by the Census Bureau, contain updated information for specific microdata files. The User Notes include corrections to the data dictionaries, announcements of errors found in the public use data files after their release, and recommended corrections for those data errors. Analysts obtaining SIPP microdata files directly from the Census Bureau will receive all User Notes that have been issued for those files at the time of purchase. Users who obtained files from other sources should contact the Customer Services Branch, Administrative and Customer Services Division, at (301) 763-4100, to request the User Notes that have been issued for the data they plan to use. User Notes are also available on the SIPP Web site (/sipp/).
Users purchasing SIPP microdata files directly from the Census Bureau receive, along with the data files, a package of technical documentation. The technical documentation includes:
The Census Bureau publishes a series of SIPP working papers. Those papers are written by authors inside the Census Bureau and by outside analysts. The series includes research papers based on SIPP data or related to the SIPP program. SIPP working papers can be obtained from the SIPP Web site (/sipp/) or ordered from the Customer Services Branch, Administrative and Customer Services Division, at (301) 763-4100.
A bibliography of works related to SIPP is available on-line from the SIPP Web site. This relatively comprehensive bibliography contains references for journal articles, research papers, and working papers that use SIPP data or that discuss the SIPP survey.
Variable metadata, available in the data dictionary, provide a complete characterization of a variable.s content. Variable metadata include all information relevant to variables that appear in the SIPP public use microdata files, including the variable name, a description of the variable, the concept label, data type (binary or character), suggested weight variable when applicable, descriptions of all possible values, and other data when applicable. A variable summary will be included for each public use variable. The summary identifies all edits, recodes, and imputations that affect the final edited output variable.
What's Available from the Survey of Income and Program Participation?, published by the Census Bureau, provides a complete directory of available SIPP data and publications. The directory lists materials available in both print and electronic formats. What's Available includes a listing of SIPP working papers, User Notes, public use microdata files, P-70 series population reports, and compilations of relevant papers published in the proceedings from the annual meetings of the American Statistical Association (ASA). What's Available from the Survey of Income and Program Participation? is updated periodically. Users can review the most recent edition at the Census Bureau Web site.
