It’s time once again for one of my favorite posts: an update of how many people are in the DNA databases! AncestryDNA just announced that they have tested 5 million people! (Note: I earn a small commission if you purchase through the links in this post. The cost is the same for you. Click here for more information.) I’ll refer you to Debbie Cruwys Kennett’s excellent blog post about AncestryDNA’s recent sales growth and their expansion into countries outside of the US.
I took the opportunity to check in with GEDmatch, and updated my graph of testing growth for them, as well. They’re at 650,000, an increase of 22% since April! The line in the graph for 23andMe is flat because they have not announced recent figures. FTDNA has never publicly revealed how many are in their autosomal DNA database; the estimate for them comes from the ISOGG wiki.
Also note that both AncestryDNA and FTDNA tests are on sale right now (AncestryDNA through the 15th, FTDNA through the end of August), so their databases should show the effects of those sales in the coming months.
Feel free to use this graph, with proper credit, in educational presentations to the genealogical community.
