Trends and history

Compared to Kantar-Sifo's previous survey from mid-December 2025, the Social Democrats have lost almost one percentage point, while the Center has increased by 0.8 percentage points and the Green Party by 0.5. The Swedish Democrats have increased by 0.9 percentage points, and the Left Party is moving forward by 0.4. The Christian Democrats are down 0.7 percentage points and approaching the threshold, while the Liberals continue to stay below the threshold after a loss of 0.5 percentage points. The Moderates have increased marginally.

Based on recent months' surveys from several institutes, the Social Democrats remain the largest party, but the trend shows some decline. The Swedish Democrats and Moderates are stable around 17–22 percent, while the Left Party and Green Party have slightly increased. The Liberals have consistently remained below the parliamentary threshold across all opinion polls for an extended period.

Method and uncertainty

Kantar-Sifo uses random sampling and telephone interviews for their surveys. As with all opinion polls, there is a statistical margin of error, meaning small changes between measurements are not always statistically significant.

Frequently asked questions about opinion polls

• What does the change in percentage points (Δ) mean?
  It indicates how much a party's support has increased or decreased since the previous measurement from the same institute.
• How often are opinion polls conducted?
  Most major institutes publish new polls every month, sometimes more frequently before elections.
• What is the parliamentary threshold?
  Parties must receive at least 4 percent of the votes in a parliamentary election to enter the parliament.
• How should the margin of error be interpreted?
  The margin of error indicates the interval within which the true voter support is likely to lie; small differences may be statistically uncertain.
• What is the difference between voter support and mandates?
  Voter support shows the percentage of voters supporting a party, while mandates show how votes are converted into seats in the parliament.
