GSIB Sibling Module           

OVERVIEW

Information about the Graduate Respondent's siblings was collected in 
the following manner:

   - In 1975, Graduate Respondents were asked about siblings including 
     those who were born alive but were no longer living.  Information 
     ascertained included: number of sisters, number of older sisters, 
     number of brothers, number of older brothers.  The Graduate 
     Respondents were asked details about living siblings: name, sex, 
     relationship, age, and level of education.  Relationship of this 
     sibling was not specified.  Information on a twin was ascertained 
     if appropriate.
   
     One of the currently living siblings was randomly chosen as a 
     selected sibling and additional questions were asked about this 
     sibling.  A random sample of these selected siblings were interviewed 
     in 1977.  In 1994, many of these siblings were interviewed again.  
     The sample included:  those who were eligible for interview in 1977, 
     and all others for whom the corresponding graduate was interviewed 
     in 1993. In 2004, these selected siblings who were interviewed in 
     1977 or 1994 were once again fielded.  
 
  -  In 1993, if the graduate was not interviewed in 1975, the questions 
     which were asked of the 1975 graduates about siblings were asked.  
     Differences between 1975 and 1993 were that 1993 graduates were 
     specifically told to include biological and adopted living
     siblings in the roster that included name, age, gender and 
     education; and when reporting total number of siblings they were 
     instructed to "count those born alive but no longer living, as well 
     as those alive now.  Also include step-brothers and step-sisters 
     and children adopted by your parents."  These details about siblings 
     were "filled into" the 1975 sibling variables. Graduates who 
     responded in both 1975 and 1993, were only asked questions about 
     selected sibling.    
   
   - In 2004, the Graduate Respondents were initially asked about any 
     siblings they grew up with who were no longer living.  The intent 
     was to learn year of death, age at death and cause of death for all 
     siblings.  Many graduates did not report information about siblings 
     who died in childhood because they did not grow up with them.  On 
     August 19, 2004, the question was changed to "Do you have any full 
     or half siblings who are no longer living?"
   
     THESE ITEMS WERE NOT ASKED FOR EACH KNOWN SIBLING BUT WERE POSED AS 
     A GENERAL QUESTION.  As a result, previously unknown siblings may 
     have been enumerated. If previously enumerated siblings were still 
     living, no additional information was ascertained about them in 
     2004.  Any siblings enumerated in previous surveys were considered 
     to be alive if not listed as deceased during this interview.  For 
     cases where total number of siblings enumerated during this survey 
     and previous surveys is less than report of siblings ever born, the 
     selected sibling is asked the question "Do you have any full or half 
     siblings who are no longer living?" during the 2004 selected sibling 
     interview.  That information will be used to "fill in" gaps in the 
     graduate respondent report if possible.

     Details about selected sibling's current occupation, and contact, 
     closeness, comparison, between grad and selected sibling were
     also obtained in 2004 graduate interview.

    Information about the Randomly Selected Sibling.  One sibling was 
    randomly selected in 1975 or 1993 (for 1975 nonrespondents).  A 
    random 1/3 sample of 1975 selected siblings were eligible for 
    interview in 1977; and siblings selected in 1975 were eligible for 
    interview in 1994.  Thus the selected sibling who is reported about
    in this graduate sibling module is the same as the sibling respondent
    in the 1977 and 1994 sibling surveys.
