* Figure 1 illustrates statistically significant net flows from November 2020 to May 2021 between the different parties. The figures indicate significant net gains and net losses as a percentage of the electorate. The flows are based on all those who stated which party they would vote for or answered “do not know” when asked which party they would vote for in an election in each survey round. The flows cannot be used to calculate total changes in parties’ proportion of voters compared with November 2020, because only statistically significant flows are presented and because there are flows between parties and the “do not know” group. (Unweighted information is available in table 22 in the table to be published on 8 June.)

Definitions and explanations

The Party Preference Survey in May 2021 was conducted with a national random sample consisting of 9 216 people entitled to vote in a parliamentary election, without an upper age limit. Answers from these people are collected through telephone interviews and online questionnaires. As in previous surveys, all available telephone numbers, both to mobile phones and fixed phones, have been used to contact the selected persons.

Among the sample persons, 29.3 percent could not be reached, 2.5 percent were unable to participate, and 17.8 percent did not wish to participate. The total non-response rate was 49.5 percent. The total number of respondents was 4 656, which corresponds to 50.5 percent. A more detailed presentation of the non-response will be made available in conjunction with the publication on 8 June.

The data was collected during the period from 28 April to 27 May.

The results are presented in the form of point estimates ± margins of uncertainty. The interval that is formed by the percent estimate ± margin of uncertainty here is a 95 percent uncertainty interval, which is an interval that, with 95 percent probability, includes the actual value of the population, if no systematic errors occur.

Next publishing will be

On 8 June, information about Political party preferences in May 2021 will be published, in total and by different demographic groups. Statistics Sweden has opted to split up the Political Party Preference Survey results to make it possible to publish “Election today estimate” as quickly as possible after completed data collection, and also to make it clear that there are two different measurements involved. “Election today estimate” is measured using the question “Which party would you vote for if a parliamentary election was held in the next few days?” while the political party preference is measured using the questions “Do you prefer one of the political parties more than the others?” and “Which party do you prefer the most?”.

The publication on 8 June will also contain information about EU and euro preferences, in total and by different demographic groups.
