Details about the new estimates
We are always looking for new ways to enhance our customers’ experiences and support them on their journeys of self-discovery. DNA science is advancing rapidly and, as a leader in this field, we remain committed to investing in ‘what’s next’. By leveraging improvements in DNA science and an increase of more than 13,000 samples in our ethnicity reference panel, we developed a new algorithm that determines customers’ ethnic breakdown with an even higher degree of precision. We’ve used the expanded reference panel and updated algorithm to add more specific regions in Asia and Europe.
The enhanced ethnicity estimates are driven by a new algorithm that analyzes longer segments of genetic information against DNA samples from Ancestry’s expanded proprietary population reference panel.
Larger Reference Panel
We've added 13,000 more samples to our reference panel, which increases our ability to identify and find the genetic signature of a region within one’s DNA.
A new algorithm analyzes longer segments of genetic information in combination with analysis of DNA samples from Ancestry’s expanded proprietary population reference panel.
To estimate your genetic ethnicity, we compare your DNA to the DNA of people with deep family histories from specific parts of the world. This group of individuals is called our reference panel. Ancestry’s unique reference panel is a collection of thousands of DNA samples from around the globe. It’s unique because most samples come from our database, and their heritage is verified through Ancestry family trees.
The newly enhanced version of our ethnicity estimate includes more regions in Asia and Europe. For example, we have expanded our regions in Asia to include Western and Central India, the Philippines, Japan, Korea, and Northern China. Also, Scandinavia can now be reported more specifically as Sweden or Norway.
This new ethnicity estimate is provided free of charge to our current AncestryDNA customers.
Questions for existing Customers
No, your new ethnicity estimate will appear in your customer dashboard whether you are logged in via mobile or desktop. If you would like to view your new results in the AncestryDNA app, please ensure you have downloaded the most updated version.
You will be able to view your previous estimate within your DNA Story for a short period so you can see how your results have evolved.
No, we can update your results using our new algorithm. You do not have to provide a new sample.
What should I expect from my new estimate?
Our new algorithm allows us to determine your ethnic breakdown with a higher degree of precision – which may mean notable changes, such as increases or decreases in percentages from your ethnic regions. Additionally, increased precision allows us to have more confidence in a customer’s results which means that low confidence regions from previous results may disappear entirely.
Don’t worry – your DNA hasn’t changed! Rather the method we use to analyze your DNA and determine your ethnicity estimate has evolved. Analyzing DNA to estimate a person’s ethnicity is at the cutting edge of science – and in a field that is evolving rapidly, there will always be developments and improvements we can make. Your latest ethnicity estimate has been calculated using a new algorithm and a larger reference panel, which allows us to estimate your ethnicity with an even higher degree of precision.
Increased precision allows us to have more confidence in a customer’s results, which means that some regions from previous results may disappear entirely.

We’re confident in the science behind this new algorithm and the accuracy of these results. The consumer genomics industry is in its early stages and these results are as accurate as possible for where the science is today. However, we will continue to use advances in science to enhance our customers’ experiences, which means that these results will evolve over time as the resolution of DNA estimates improve. A good example of this is our ability to break up large regions into smaller, more specific regions – which means you may see more precise geographies in your ethnicity estimate over time.
Your latest ethnicity estimate has been calculated using our new algorithm, which allows us to estimate your ethnicity with a higher degree of precision. That said, your DNA is only one element of a much larger picture, and your family history and relatives will play an important role in your genetic make-up, even if they are not specifically reflected in your ethnicity results.
While we each inherit 50% of our DNA from our father and 50% from our mother, we do not get an equal 50/50 split of all of our parents’ DNA. This means, that if your parent only has a small percentage of DNA from a specific region, you might not inherit any of that portion of their DNA.
The change will not affect your DNA matches.
The change will not affect sub-regions/migrations, as they are determined using a different methodology. Ancestry’s proprietary science determines migrations and sub-regions by identifying groups of people in our DNA network who have more matches to each other than to people in other parts of the network and searching the linked family trees of people in the community to identify ancestors who were in the same area at the same time.
AncestryDNA ethnicity estimates are based on available data. So, if Ancestry does not have sufficient data, your ethnicity estimate will most likely be reflected in neighboring regions. However, it is important to note two factors. First, some populations do not differ enough at a genetic level to be distinguished as separate regions. Second, countries change over time, and boundaries on a map today do not necessarily represent genetic boundaries, so there may be population groups or countries that never fall into a single region.
