23andMe have released their Ancestry Composition geographic ancestry analysis feature. It is very interesting. They have 22 populations included in the analysis.
I’m 99.2% British & Irish. My global resolution is 99.9% European. My regional resolution is 99.3% Northern European & 0.6% Nonspecific European.
Here is a chromosome view of the analysis. I have Northern European segments on chromosome 6 and 11.
