Opinion polling for the United Kingdom European Union membership referendum

This page lists the public opinion polls that have been conducted in relation to the United Kingdom European Union membership referendum.

Analysis of polling suggests that younger voters tend to support remaining in the EU, whereas those older tend to support leaving, but there is no gender split in attitudes.^[1]

Standard polling on EU membership

This list is incomplete; you can help by expanding it.

The tables and figure below show polling on whether the UK should be in or out of the EU. Polling generally weights the sample to be nationally representative. Polls are usually conducted within Great Britain, with Northern Ireland normally omitted from the sample.^[2] This has historically been the case in UK opinion polling because Northern Ireland has a different set of political parties from the rest of the UK, reflecting the political divide between unionism and nationalism or republicanism.^[2]
