Labour finished first in Norway’s 2025 election. What the campaign focused on, and how research shaped it.
Jonas Gahr Støre and the Labour Party (Arbeiderpartiet) finished first in Norway’s parliamentary election on September 8, 2025. Data Sciences worked with the campaign on research and data throughout the race. Nine months before the election, Arbeiderpartiet faced a steep climb. The party worked with Data Sciences to navigate a complex political landscape and build a winning coalition of voters.
Data Sciences contributed predictive forecasting of polling, rolling message testing and voter segmentation, turning raw data into insights the campaign could act on. These findings helped the campaign understand shifting priorities among voters and put resources where they mattered most. Data Sciences’ analysis helped sharpen Arbeiderpartiet’s voter outreach. It identified the most receptive demographic groups and regions, the narratives that resonated most, and the most effective ways to mobilize supporters in the final stretch. “We are incredibly proud to have supported Arbeiderpartiet in this historic win,” said Amund Vik, VP International, Strategy and Advisory at Data Sciences. “This victory is a powerful demonstration of what is possible when data is transformed into decisive action.” Against a backdrop of narrow polls and strong competition, Arbeiderpartiet emerged with a renewed mandate to govern, finishing first with 28% of the vote and 53 seats. From Canada to the UK and Norway, Data Sciences has supported parties and campaigns with research, data and digital since 2014.
