Instructions for building the Integrated Surveys 1981-2008 data file

The WVS Longitudinal file is now available in different formats. In order to merge with EVS you may wish to convert their SPSS file to the same format.

In order to build the file, follow these simple steps:

  1. Download the last official EVS and WVS longitudinal aggregates from the official locations:
    • EVS: Online Study Catalogue ZACAT: Longitudinal Data File 1981-2008 (ZA4804)
    • WVS: WVS Website Download data files section.
  2. Open the WVS Longitudinal file and merge (add cases) the EVS file. Use this order because the WVS includes more variables. The add cases command varies depending on the statistical program (use ADD FILES from SPSS, APPEND command for STATA).
