Since 2002, the CEP has been responsible for implementing post-election surveys following legislative elections. In addition, a survey was also carried out following the presidential elections in 2006. These datasets have all been deposited at the Portuguese Social Research Arquive (http://www.apis.ics.ulisboa.pt).

All the studies below include the corresponding CSES Module; two studies include parts of the CNEP Module (2005 and 2015). In addition to these international questionnaires which were implemented, each study also includes items which are election-specific.

Here you will find a document with all the questions included since 2002. 

In 2023, an integrated dataset with all post-legislative elections collected since 2002, was produced, which can be found below.
