For the years 1999 and 2000, we have also included referendums. These referendums have been used to calculate an alternative index, where each referendum add to the value of the participation score. This procedure is documented in the preface to the 1999-2000 update. A index based on this alternative procedure has been prepared for download, but does only cover the years 1999 and 2000.
The Excel and ASCII files are exported directly form the main Access 2000 database, while the Stata and SPSS files are converted using Stat-Transfer. The Excel, ASCII, Stata and SPSS files contain only the calculated index.
