Official polls for Spain's 29 November general election in Catalonia: CIS and CEO

Polls from the two public bodies that run them: the Centro de Investigaciones Sociológicas (CIS), part of the Spanish government, and the Centre d'Estudis d'Opinió (CEO), part of the Catalan government. Their vote and Congress seat estimates for Catalonia and, where they give them, for each province, with each poll's technical sheet. No private or media polls.

No figures from 24 to 29 November

Spanish electoral law bans publishing, broadcasting or reproducing election polls in the five days before the vote. From Tuesday 24 November at 00:00 to Sunday 29 November at 21:00 (Madrid time), when the last polling stations close in the Canary Islands, this page shows no poll figures.

Official documents

Checked on 5 November 2026.

Not yet published

  • Centro de Investigaciones Sociológicas (CIS): Study 3584, 2026 general election pre-electoral survey. No date announced. The Junta Electoral Central recorded its start at its session of 15 October (agreement 267/2026), and on 22 October the CIS said it could not yet say when fieldwork would end. If it comes out before the vote, it has to be by 23 November at the latest: the law bans publishing polls from 24 to 28 November. At the 2023 general election, the CIS pre-electoral study included a seat estimate for each province. The CIS October barometer (study 3582) gives an estimate for Spain as a whole only. Official website. Checked on 5 November 2026.
  • Centre d'Estudis d'Opinió (CEO): Political Opinion Barometer, 3rd wave 2026, or a pre-electoral survey. No date announced. The barometer's technical sheet plans three waves in 2026. The CEO has not announced a date for the third, and the register of opinion studies lists no CEO pre-electoral survey for 29 November. Official website. Checked on 5 November 2026.

How to read an estimate

An estimate is not a result. Each body starts from a sample's answers and applies its own model to work out each list's likely vote; the method is set out in its reports. That is why the CIS and the CEO can give different figures, often as ranges.

Seats are allocated by province. Catalonia elects 48 deputies (32 in Barcelona, 6 in Girona, 4 in Lleida and 6 in Tarragona), by the D'Hondt method among lists with at least 3% of the valid votes in each province.

This page reproduces the figures exactly as each body publishes them, with the lists in the source's order, neither rounded nor combined.

What the electoral law says

Article 69 of the electoral law (LOREG) governs election polls. Under its first paragraph, anyone publishing one must give its technical sheet: the name and address of who ran it and who commissioned it, the sampling system, sample size, margin of error, level of representativeness, how respondents were selected, the fieldwork dates, and the full text of the questions with the number of people who did not answer each one. That is why every poll on this page carries its sheet and a link to the official questionnaire.

In the five days before the vote, 24 to 28 November, the law bans publishing, broadcasting or reproducing election polls in any medium (paragraph 7), and the Junta Electoral Central enforces it (paragraph 2). This page also shows none on polling day until the last polling stations close, in the Canary Islands, at 21:00 Madrid time.

Official results on 29 November

On the night of 29 November, Spain's Ministry of the Interior publishes the provisional count as polling stations report. It has not yet announced its results website; until it does, the references are the official election website and the 29N page on Infoelectoral. The Catalan government has a 29N information page.

How the night works and when results become official: election night on 29 November. Who is standing in each province: Congress and Senate candidates. How and where to vote: how to vote in Catalonia. Past results by town: election results by town.

Frequently asked questions

When can polls not be published before the 29 November election?

From Tuesday 24 to Saturday 28 November, the five days before the vote (article 69.7 of the LOREG). This page removes the figures from 24 November at 00:00 until Sunday 29 November at 21:00 Madrid time, when polling stations close in the Canary Islands.

Which polls are official?

Those of the public bodies that run election polls: the CIS, part of the Spanish government, and the CEO, part of the Generalitat de Catalunya. Both publish each study's technical sheet, questionnaire and microdata.

Why do the CIS and CEO polls differ?

They use different samples, fieldwork dates and estimation models. Each explains its method in the results report linked from its sheet.
