1968-1992 Individual File, Release 3

  1. Background

    2. Errors were detected in the 1985-1992 Childbirth and Adoption History file, release 2, from which V32009-V32032 in the 1968-1992 Individual file, release 2 were derived. A detailed description of the changes in the 1985-1992 Childbirth and Adoption History file was provided when it was re-released. After a revised version of the 1985-1992 Childbirth and Adoption History file was created, a revised version the 1968-1992 Individual file with corrected values for V32009-V32032 was created.

    The following corrections have been made to the 1968-1992 Individual data file:

    1. The most significant changes are to V32015 (Marital status of mother at time of individual's birth).
    2. Minor changes have also been made to other variables derived from the childbirth and adoption history information (V32009-V32014, V32016-V32032).
    3. V32700 (RELEASE NUMBER) has values of "003" for all records.

    These changes affect the 1968-1992 Individual file on the CD-ROM issued in December 1995 and the version on the Internet issued in December 1995.

  2. Advice to Analysts

    3. Analysts of the 1968-1992 Individual file who have used affected variables in their analysis, particularly V32015, should download a new version of the 1968-1992 Individual file from the PSID Website and incorporate this file into their analysis routines.
