Note: Codebooks contain frequency data from the private data release. For some variables, these differ from the frequencies in the public release.

Economic Imputations

Imputation Data 

OVERVIEW

The data contain imputed data values for missing data on economic variables. 
For graduates imputed values are available for the  1975, 1992, and 2004 waves
of data.  For siblings imputed data are  available for the 1994 and 2005 wave. 


For each variable, five separate imputations are available. The first 6-7
characters in the imputed variable names match the first 6-7
characters in the original analysis variables.  The  imputed variable names
then add an additional two characters.  The  first is the letter "I"
and the second is a digit between one and  five indicating the imputation
number.

For more information on how the imputations were created and how to use them
data please see cor1014 in Appendix L.

Please also refer to the original analysis variables for additional notes and
restrictions.
