Ethnicity Estimate 2019 White Paper

The AncestryDNA science team has developed a fast, sophisticated, and accurate method for estimating the historical origins of customers’ DNA going back several hundred to over 1,000 years. Our newest approach improves upon our previous version in the number of possible regions that a customer might be assigned (from 43 to 60) as well as an increase in accuracy to both regions assigned and the percentage assigned to each region. We have added many new regions as well as made improvements to the composition of our reference panel, resulting in more accurate estimates overall. Given the cutting-edge nature of this type of science, we will continue to refine our approach and improve estimates.
