Opinion polling on Welsh independence

Opinion polling on Welsh independence is continually being carried out by various organisations to gauge public attitudes to independence. The dates for these opinion polls range from January 2007 to the present day. Polling was initially sporadic, but it has been carried out almost every month since January 2021. The question typically asked by pollsters is "Should Wales be an independent country?".
