How to Download Your Ethnicity Data from 23 and Me

Share the knowledge!

If you did your DNA test with 23 and Me, you have access to a really amazing bit of information pertaining to your ethnicity estimate, also known as your Ancestry Composition report.  Everyone else who does genetic genealogy is, or at least should be, very jealous of you!  You have the ability to download your ethnicity data in order to see exactly which DNA segments correspond to specific ethnicities.

In this post, I’ll teach you:

  • What the ethnicity data can tell you (i.e. why you should download it)
  • How to download your ethnicity data from 23 and Me
  • What to do with your ethnicity data once you’ve downloaded it

Props for 23 and Me:  I really respect 23 and Me for allowing its users to download this data – such an amazing tool and wonderful information to have access to.  If you didn’t test with 23 and Me, it’s probably worth doing a test only to get access to this data (though you’ll learn other cool things about your ancestry, too)

Why you should download your 23 and Me Ancestry composition ethnicity data

While it’s wonderful to look at a pie chart or a list of percentages related to our “ethnicity”, wouldn’t it be great if you could access information that could help you figure out exactly where those ethnicity percentages may have come from?  This is exactly the type of thing that you could learn from downloading your data.

Let me show you a little example related to my small percentage of Ashkenazi Jewish.  I opened up the file containing the information that I downloaded in Notepad.  You can open it in Excel or even Word.  You can see in the image below that I have six segments on Copy 1 of five chromosomes that match the 23 and Me Ashkenazi Jewish profile.  The data tells me the exact start and end point of these segments:

For someone who is very interested in DNA and genealogy (or genetic genealogy, as it is often called) this type of information can be exceptionally helpful.  Once I figure out which side of my family I got Copy 1 of my chromosomes from (maternal or paternal), then I might be able to find DNA matches who match me on these segments.  Once I have groups of DNA matches on these segments, I can examine their family trees and possibly spot the ancestors from whom I inherited these segments.

And of course, once I spot the ancestors from whom I inherited my Ashkenazi Jewish ancestry, I can research them with the knowledge that they have Jewish roots – a helpful detail in genealogy.

Sounds great, right?  Don’t worry, I will give you a great suggestion about what to do with this data at the end of this post.

So, without further ado…

How to download your ethnicity data on 23 and Me

The first thing that you’ll do is log in to your 23 and Me account.  From your main dashboard, click on “Ancestry”, as seen in the image below, to access your Ancestry reports:

Next, click anywhere on the Ancestry Composition line to access this report:

Once you are looking at your Ancestry Composition report on your 23 and Me account, you can scroll down to the bottom of the ethnicity percentages (about 1/3 of the way down the page) and click on “See All Tested Populations”:

Finally, once you scroll down to the end of all of the potential regions that they tested your DNA for, you’ll see an option to download your DNA.  It’s about 3/4 of the way down the page, right above where they have information about their reference data sets:

Choose confidence level for downloading 23 and me ethnicity data

You’ll notice that you can choose the “confidence level” for your download.  The default is 50%, but you can use the dropdown menu to change this to 50%, 60%, 70%, 80%, or 90%.  I recommend downloading the 50% (speculative) and the 90% files.  The data in the file containing information that has a 50% confidence level, while speculative, can contain valuable information.  You can decide whether to use it, or not.  The data in the 90% confidence level file will be more general, but still good to have for reference.

Alternatively, you can explore the confidence levels in the chromosome painting part of your Ancestry Composition report and see at which confidence level the ethnicity that you are most interested in researching still appears (i.e. 70%) and download the ethnicity data at that confidence level.

What to do with ethnicity data file from 23 and Me

Unless you’ve been doing genetic genealogy for years, you probably don’t have a big spreadsheet with DNA segment information on all of your DNA matches.  To be honest, neither do I!  I like to use something much more fun, and a whole lot easier.  There is a free site called DNA Painter.  This site helps you easily map your chromosomes, assigning individual DNA segments – via information gathered from chromosome browsers – to individual ancestors.

(Helpful post is in the works about exactly how to import ethnicity into DNA Painter)

And guess what?  Just like we can “paint” in a match (super easy – it’s automatic), we can paint our DNA segments with our ethnicity data, too.  The only thing that gets tricky is knowing which copy corresponds to your maternal and paternal lines.  Once you figure this out, though, you can easily spot which ancestors (through DNA matches that you have painted) correspond to which ethnicity regions.

Conclusion

I hope that this post gave you an idea about what to do with your ethnicity data from 23 and Me, and more interestingly, what you might be able to learn from it.  If you have any questions or comments about something that you read in this post, I would love to hear from you in the comments.

Thanks for stopping by!
