The ESS Data and Documentation section was updated 26th of November 2014 with a cumulative data file for the first six rounds of the ESS.
The cumulative data are available from the ESS Cumulative Data Wizard, where users can customise their own subsets of data in different formats. The ESS Cumulative Data Wizard gives access to cumulative data from countries that have been included in the integrated ESS files in two or more rounds. All variables that have been asked in more than one round are included in the cumulative data file.
