200+ communities
now in Scandinavia

Your results might point you to the Arctic North, where you can explore new communities that may connect you to a rich Nordic heritage.

As AncestryDNA® grows, so do the possibilities.

We’re able to provide this level of detail thanks to our patented Genetic Communities™ technology, powered by our unique combination of the world’s largest consumer DNA database and the largest network of family trees. We’re always working to improve your results to give you the best possible experience

Frequently asked questions about our communities

  • If you are included in one of these new communities, you’ll find them in the “Additional Communities” section at the bottom of your ethnicity estimate, or nested beneath an ethnic region (the regions with percentages). Communities do not have a percentage assigned to them and are marked by a circle surrounded by a dotted line. They are identified using our patented Genetic Communities™ technology, by analyzing genetic connections between groups of AncestryDNAⓇ members. Using public family trees, ethnicity data, and historical records, we determine where this group of people lived over time. We’ve identified over 900 communities this way. These groups identify areas where your ancestors may have lived more recently, between 1700-1975.
  • Your ethnicity estimate includes regions based on two different scientific processes: the AncestryDNA reference panel and Genetic Communities™.

    The AncestryDNA reference panel is made up of people who have long-standing, documented roots in a specific geographic area. We compare your DNA to this reference panel to determine your possible origins dating back hundreds to more than a thousand years ago. Regions with a solid circle in your results are based on the reference panel. These regions also have percentages assigned to them.

    The Genetic Communities™ process detects groups of AncestryDNA members who are most likely connected because they share recent ancestors who came from the same community (such as Ulster Irish) or culture (such as Mormon Pioneers). Using our Genetic Communities™ technology, we analyze genetic connections between groups of AncestryDNA members. We then use public family trees, ethnicity data, and historical records to determine where this group of people lived over time. Over 900 communities have been identified this way. These groups identify areas where your ancestors may have lived more recently. Regions with a dotted circle are based on Genetic Communities™. These communities do not have a percentage assigned to them.
  • With this update, you might lose one of the communities in your estimate. Most customers who have lost a community will find that it has been replaced with a new, smaller community. With this release, we’ve broken many larger communities into smaller ones.

    Sometimes people lose a community without a replacement. This usually happens when the confidence score for one of these communities was low. The number of samples in our database has grown since we first released these types of communities. This additional data allowed us to find hundreds of new communities, but it also refined how we classified who should be in these communities. Based on these new classifiers, some people whose link to one of these communities was already low may lose that community in their updated AncestryDNA results.
  • Your results may change in the future for a couple of reasons. First, because our Genetic Communities™ technology is new, cutting-edge science, it is constantly being updated and refined. As we update how we identify and define our communities, your results may change. Second, as we add more and more customers to our AncestryDNA database, we hope to increase the number and granularity of the regions we offer. This means that in the future, you may be added to new regions or to a newly refined region.
