Opinion polling on Scottish independence

Last updated

Opinion polling on Scottish independence is continually being carried out by various organisations. This article concerns well over 240 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.

Contents

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.

Graph Methodology

The graphs include all polls from the main table, excluding those which are noted as using non-standard questions.

The date associated with each poll is the mid-point of the survey period, i.e (start+end)/2.

The centered moving averages are the averages of the last 10 polls, weighted by sample size. The date of the moving average is the weighted average poll date. The value of the moving average is variously the percentage for Yes, No, Undecided and the margin ex-undecideds of those polls.

The margin ex-undecideds value for each poll is calculated as (No-Yes)/(No+Yes).

The final chart is the distribution of a given organisations polls compared to the moving average margin ex-undecideds. The value of the moving average at the poll's date is computed by linear interpolation between adjacent values of the moving average. The difference between that value and the poll's value is shown as a distribution.

Frequently time axis dates may be in the future for long-term graphs. This is done to avoid truncation of datapoints at the edge of the chart area.

Polls using Remain / Leave Question

Some organisations have chosen to commission polls that adopt the remain / leave formulation that was used in the 2016 United Kingdom European Union membership referendum.

The use of this format has been criticised by pro-independence politicians. SNP depute leader Keith Brown said in September 2019 that it was "a deliberate bid to confuse independence with Brexit".

Polls on a "de facto" referendum

On 23 November 2022, the UK Supreme Court ruled that the Scottish Parliament does not have the power to unilaterally hold an independence referendum without the consent of the Westminster Parliament. [2] Following that judgment, the SNP reiterated its intention to campaign in the next UK general election as a de facto independence referendum. Question asked is stated in notes field.

Scottish Social Attitudes Survey

Since devolution, the annual Scottish Social Attitudes Survey has contained a question on independence.

Respondents are asked Which of these statements comes closest to your view?

  1. Scotland should become independent, separate from the UK and the European Union
  2. Scotland should become independent, separate from the UK but part of the European Union
  3. Scotland should remain part of the UK, with its own elected parliament which has some taxation powers
  4. Scotland should remain part of the UK, with its own elected parliament which has no taxation powers
  5. Scotland should remain part of the UK without an elected parliament.

A report released in 2017, entitled From Indyref1 to Indyref2? The State of Nationalism in Scotland, detailed the previous responses from this survey by grouping options one and two as "independence", options three and four as "devolution" and option five as "No Parliament".

<span class="mw-page-title-main">Bradley effect</span> Theory about discrepancies between opinion polls and election results in the United States

The Bradley effect is a theory concerning observed discrepancies between voter opinion polls and election outcomes in some United States government elections where a white candidate and a non-white candidate run against each other. The theory proposes that some white voters who intend to vote for the white candidate would nonetheless tell pollsters that they are undecided or likely to vote for the non-white candidate. It was named after Los Angeles mayor Tom Bradley, an African-American who lost the 1982 California gubernatorial election to California attorney general George Deukmejian, a white person, despite Bradley being ahead in voter polls going into the elections.

This is a list of opinion polls for the 2007 Scottish Parliament election. The first figure for each party is for the 1st, first-past-the-post, constituency, vote; the second figure is for the 2nd, proportional representation, regional, vote. The Scottish Greens and the Scottish Socialist Party ran only one constituency candidate each in the 2007 election so constituency values in polls for those parties have little meaning.

Full fiscal autonomy (FFA) – also known as devolution max, devo-max, or fiscal federalism – is a particular form of far-reaching devolution proposed for Scotland and for Wales. The term has come to describe a constitutional arrangement in which instead of receiving a block grant from His Majesty's Treasury as at present, the Scottish Parliament or the Senedd would receive all taxation levied in Scotland or Wales; it would be responsible for most spending in Scotland or Wales but make payments to the UK government to cover Scotland or Wales's share of the cost of providing certain UK-wide services, largely defence and foreign relations. Scottish/Welsh fiscal autonomy – stopping short of full political independence – is usually promoted by advocates of a federal United Kingdom.

<span class="mw-page-title-main">Opinion polling for the United Kingdom European Union membership referendum</span>

The referendum on EU membership took place on 23 June 2016. Opinion polling for the United Kingdom European Union membership referendum was ongoing in the months between the announcement of a referendum and the referendum polling day. Polls on the general principle of the UK's membership of the European Union were carried out for a number of years prior to the referendum. Opinion polls of voters in general tended to show roughly equal proportions in favour of remaining and leaving. Polls of business leaders, scientists, and lawyers showed majorities in favour of remaining. Among non-British citizens in other EU member states, polling suggested that a majority were in favour of the UK remaining in the EU in principle, but that a similarly sized majority believed that if the UK were only able to remain in the EU on renegotiated terms then it should leave.

A second referendum on the independence of Scotland from the United Kingdom (UK) has been proposed by the Scottish Government. An independence referendum was first held on 18 September 2014, with 55% voting "No" to independence.
