DNA ethnicity–FTNDA old vs. new

FTDNA updated their algorithms and most people have a change in their ethnicity results.  All of the autosomal DNA sites do this from time to time so I dug out some old screenshots to compare them side by side.

And the moral of the story is, every company uses different algorithms and reference populations. Every company updates this information from time to time. It is normal to see different numbers from company to company and it is normal to see different numbers after a company updates. 23andMe is considered to be the most accurate when it comes to ethnicity predictions.  When I look at my 23andMe results they do correspond with my paper trail.
