More people tested means stronger confidence.

Our existing DNA reference panel was already impressive, but this new update includes even more DNA samples. With over 40,000 samples in our reference panel, this allows us an even better understanding of genetic signatures around the world for a more detailed picture of where you came from.

Our larger panel allows us to better distinguish between adjacent regions—like Australia and New Zealand—as well as break down larger regions, like East Asia and the Americas, into more detail.

Frequently asked questions about our updated ethnicity estimate.

Details about the new estimates

  • We are always looking for new ways to enhance our customers’ experiences and support them on their journeys of personal 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 23,000 samples to our ethnicity reference panel, we’ve been able to determine most customers’ ethnic breakdown with an even higher degree of precision. We’ve used the expanded reference panel as well as our Genetic Communities? technology to now make available more than 1,000 regions to AncestryDNA customers.

  • Creating an ethnicity estimate based on your DNA sample is a complex process based on probability, statistics, shared DNA, and ongoing research and science. AncestryDNA calculates your ethnicity estimate by comparing your DNA to a reference panel made up of thousands of people. Because reference panels and the way we analyze your DNA both change as we get more data, your ethnicity results can change as we get more data, too. See http://www.farleydds.com/lp/ethnicity-estimate/reading-your-ethnicity-estimate for a deeper dive into your ethnicity estimate.

  • Larger Reference Panel
    Our enhanced ethnicity estimates are made possible thanks to increases in the proprietary set of DNA samples behind the AncestryDNA reference panel. We've added 23,000 more samples to our reference panel, which increases our ability to identify and find the genetic signature of a region within one’s DNA.

  • 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. The unique AncestryDNA 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 Europe, the Americas, Oceania, and South Asia. For example, we have expanded our regions in the Americas to include indigenous Mexico, Yucatan Peninsula, Puerto Rico, Haiti & Dominican Republic, Cuba, Colombia & Venezuela, Eastern South America, Central America, and the Arctic. Also, Polynesia can now be reported more specifically as Tonga, Guam, and Samoa.

  • This new ethnicity estimate is provided free of charge to our current AncestryDNA customers.

Questions for existing Customers

  • We are phasing the update over time to ensure individual attention is given to delivering each result; therefore, you may see your results earlier or later than others.

  • 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 and download the prior version of your ethnicity estimate in DNA Story for 90 days post update.

  • No, we can update your results without you having to provide a new sample.

  • When you receive your DNA results, they’ll include the latest ethnicity?estimate.

  • As soon as your new results are ready, we will automatically apply this update. The new results will replace your current ethnicity estimate.

What should I expect from my new estimate?

  • Our expanded reference panel 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.

  • Don’t worry – your DNA hasn’t changed! Rather the reference panel we compare your DNA to determine your ethnicity estimate has increased dramatically - we now have over 40,000 samples in our panel to provide results that are even more precise. 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 determined using 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 our proprietary 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 determined using a larger reference panel, 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 AncestryDNA ethnicity estimate.

  • 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 communities, as they are determined using a different methodology. Our proprietary Genetic Communities? technology determines communities 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 do not fall into a single region.
