Political Party Preference Survey in May 2026 - Political party preferences
Political party preferences in May 2026
Statistical news from Statistics Sweden 2026-06-10 8.00
The Political Party Preference Survey shows in which demographic groups the political parties have their greatest support. Political party preference does not refer to any specific political level, and no account is taken of whether or not a person would vote. This survey also presents the EU, euro and NATO preferences of the electorate.
On 4 June, Statistics Sweden published estimates of what the election results would have been if an election had been held in May 2026. Based on the same survey, estimates of political party preferences in the electorate are presented here. Political party preference refers to the political party a person prefers the most, which is not necessarily the same as the political party they would vote for in a parliamentary election.
The difference between the measurements is:
- Political Party Preference (preferred party) does not refer to any specific political level, such as parliamentary elections, and no account is taken of whether or not a person would vote.
- The “Election Today” estimate refers to the results of a hypothetical election in May and take into account whether or not the person would vote.
Political party preferences are compared below with results of a hypothetical parliamentary election in May 2026.

Definitions and explanations
The Party Preference Survey in May 2026 was conducted with a national random sample consisting of 9 260 persons entitled to vote in a parliamentary election, without any 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, 29.0 percent could not be reached, 2.2 percent were unable to participate, and 21.0 percent did not wish to be participate. The total non-response rate was 51.0 percent. The total number of respondents was 4 542, which corresponds to 49.0 percent. A more detailed presentation of non-response is available in table 23 of the publication “Political Party Preference Survey May 2026”.
The data was collected during the period from 28 April to 28 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 inaccuracy interval, which is an interval that, with 95 percent confidence, includes the actual value of the population, if there are no systematic errors.
