The ESS source questionnaire consists of a collection of questions that can be classified into two main parts – a core section and a rotating section.

Until ESS Round 7, the 21-item human values scale and experimental tests used to be part of the supplementary questionnaire, which is now incorporated in the main questionnaire.

The page outlines the purpose and content of each section, while their development is documented on the Source Questionnaire Development page.
