Opinion polling on Scottish independence is continually being carried out by various organisations. This article concerns the nearly 300 polls carried out since the 2014 Scottish independence referendum. Polling conducted before the referendum can be found here. Polls listed here, except as noted, are by members of the British Polling Council (BPC) and abide by its disclosure rules.
The main table includes primarily those polls which ask the same question as the 2014 referendum: "Should Scotland be an Independent Country?". Other tables reflect different questions on independence, which may produce different results. Any factors that might impact the poll result, such as excluding 16 and 17-year-old voters, are recorded in the 'Notes' column. The table also lists some events that may have impacted on polls including Brexit, COVID-19 and party leadership changes.
Polls in the main table, using the same question, still show systematic differences between different polling organisations. Therefore to discern trends it is helpful to compare a poll with previous results from same pollster.
