Geocode Codebook Supplement

The geocode codebook on the CD provides detailed information on each geocode variable, including reference number, variable description, coding information, frequency distribution, file name, variable name, and source of the variable (whether it is a direct questionnaire pickup or a created variable). Included are references to pertinent attachments and appendices providing supplementary coding and variable creation procedures. Variables are grouped within the geocode codebook according to the year with GEO79 variables followed by GEO80 and so forth. Note: Hardcopy versions of the geocode codebook and numeric index are not provided to CD users since the disc software allows users to generate their own documentation.
