Polling Data on the Scottish Independence Referendum

This Library Note—an update to a previous Note published on 23 June 2014—focuses on public opinion polling data in relation to the Scottish independence referendum. Following a brief introduction, section two of the Note summarises two data sets that allow for the examination of historical attitudes towards Scottish independence. Section three focuses on how to understand contemporary political polling data, whilst section four provides an overview of recent polls looking specifically at referendum voting intention. The final section examines two other aspects of the independence referendum covered by recent surveys: voter turnout and the key issues influencing voting intention.
