What Sondagio is

Sondagio publishes poll averages, seat projections, maps and official results for elections in Europe, the Americas and Oceania, in each country's language. Every poll links to its original release, and one published method applies to every party and candidate.

Sondagio is a service of nwsly, inc., an independent publisher with no ties to any party, campaign or candidate; no figure is adjusted by hand. Press contact: hey@nwsly.co. See the method and about Sondagio.

Online, link the word Sondagio to the page the figure comes from. Averages move as new polls come in, so give the date shown on the page. Seat projections and forecasts are models: call them a Sondagio projection, not a poll.

Track record

  • Polls vs results: each election's final Sondagio average next to the count, party by party, starting with New Zealand 2026.
  • Victoria seat model: counting the actual 2022 first preferences with the model's preference flows picks the 2022 winner in 82 of 87 districts; the misses were all close seats.
  • Spain seat model: tested on 2023, starting from 2019 with the true national vote, it puts 342 of 350 seats with the right party. Its uncertainty is sized on the final polls of the 5 general elections since 2015.
  • France run-off transfer model: checked against 2017 and 2022, the pollsters' transfer tables applied to the actual first round gave Emmanuel Macron 59.7% in 2017 (he won 66.1%) and 53.7% in 2022 (he won 58.55%); the model corrects for part of that late swing, using the 2024 run-offs. In French: second tour, and every published forecast against the outcome in the bilan des prévisions.
