A list of data sources by countries of archive locations holding sample surveys of voting behaviour in referendums related to EU issues.
Below is one example of an interactive table providing a list of all EU related referendums to date [to be moved to public opinion]. It draws on the report of Mendez and Mendez (2017) for the European Parliament. The table can be organised according to the thematic categories of the report. We will be adding new data sources and interactive data tables as part of the ongoing research.
