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.
