Last week, AncestryDNA announced that their database has reached 3 million people, and that they had sold 1.4 million kits on top of that in the last 3 months of 2016. See “Ancestry Sets AncestryDNA Sales Record Over Holiday Period and Fourth Quarter” for more information.
This means that by summer or fall of 2017, the database is likely to reach 5 million people.
Many people have noted that many of these new test-takers will undoubtedly not have trees. That’s true, unfortunately, although it is a challenge rather than an absolute roadblock. It is an opportunity for experienced genealogists to engage new genealogists and encourage and help them. Indeed, many of them will never add a tree, and that will be very, very frustrating. But at least a small fraction of those will have a good reason for not doing so. The majority without trees will likely either not know how to do it, or may only be interested in ethnicity.
