Codebook of Variable Labels and Label Values

The Codebook of Variable Labels and Label Values contains four items of information for each variable in the core data files.

  • Variable Name--Every variable has a name which can be up to eight characters in length.
  • Variable Label--Variable labels are up to 30 characters in length. They are more descriptive, but do not exist for all variables.
  • Label Name--Some variables are assigned labels to help interpret response codes. For instance, the variable named gender is assigned a label which matches the numeric responses to male or female.
  • Label Codes or Values--These are the code values for the label names.
