6 articles on Scandinavia, ancient-DNA research written up for readers who want the evidence, not just the headline.
The Nordic countries are the best-sampled corner of the ancient-DNA map: hundreds of dated genomes from Mesolithic foragers, Funnel Beaker farmers, Corded Ware herders and the Viking Age. These articles read that record country by country, Denmark, Sweden, Norway, Finland and Iceland, and explain what a modern Scandinavian genome models as, and what a Viking Age match can and cannot mean.

There is no Viking percentage, because Viking was an occupation and the Viking Age population was mixed. What a DNA test can honestly measure: resemblance to published Viking Age individuals, qpAdm models with Scandinavian sources, and shared segments with the people themselves.
Norway was settled from the north as well as the south, took up farming late, and sent the Viking Age west to the British Isles and Iceland. What ancient DNA shows about Norwegian ancestry, the fjord-valley structure of the modern country, and the Sámi in the north.
Sweden's ancient genomes record foragers who came in through two doors, farmers and hunters who lived side by side for a thousand years, a Battle Axe arrival, and a Viking Age that ran east. What ancient DNA shows about Swedish ancestry, the north to south structure, and the Sámi as a distinct population.
A hundred ancient genomes from Danish soil record two near-complete population turnovers, a stable Bronze Age and a Viking Age that exported the Danelaw and imported ancestry in return. What ancient DNA shows about Danish ancestry, and how to model a Danish genome era by era.
Denmark, Sweden and Norway share a genome written by two prehistoric turnovers and one famous exchange: the Viking Age imported as much ancestry as it exported. The ancient-DNA story, and how to read a Scandinavian genome.
A 442-genome Viking study reveals regional Scandinavian ancestry, family expeditions, migration and Viking identities beyond genetic ancestry.
