COR612A

SUMMARY:  This is a comprehensive list of all job variables created for 1975-77
data.  [It does NOT include any reference to 1957, tax, and 1964 variables.]  
For a review of ALL ind/occ/cw and related variables see MEMO122.  

INDUSTRY -            NOT available for all variables

OCCUPATION -          IS available for all variables

CLASS/WORKER -        NOT available for all variables

MAJOR INDUSTRY -      Calculated the same for all variables - 
MAJIND                COR521C twelve categories (originally 
                      created in COR226 then corrected in COR569)

MAJOR OCCUPATION GROUP II - Requires CW, calculated whenever possible - 
MAJOCC                COR521C seventeen categories - created originally 
                      in COR226 and code repeated in COR521C.
                      Called Occupational Categories throughout original
                      codebook!  CHANGE ALL 17 CATEGORY MAJOR OCCUPATION
                      GROUP CODES TO BE Major Occupational Groups!  This
                      will make the variable names consistent with those
                      used for the Wave 2 data.  Major Occupational Groups
                      will always refer to the 17 category version of the
                      variable.

MAJOR GROUP -         Does not require CW, only calculated when GROUP II 
                      not possible - COR226 twelve categories called 
                      Major Occupational Groups throughout original codebook!
                      CHANGE ALL 12 CATEGORY MAJOR OCCUPATION
                      GROUP CODES TO BE Occupational Groups!

Creation of Status (Duncan) Scores:

     With all data present:  use COR521C - DUNC=Status

     When class of worker is missing: use COR613A

     When industry is missing: use COR613B
            which will map directly from occupation lines into male prestige
           scores and is not dependent upon industry.

Creation of Prestige (Siegel/NORC) Scores:

     With all data present:  use COR521C - SIEG=Prestige

     When class of worker is missing:  also use COR521C - SIEG 
           because class of worker is not needed for these scores.

     When industry is missing:  use COR613B
           which will map directly from occupation lines into male prestige 
           scores and is not dependent upon industry.
