Question about Google Analytics and Language

When I go into Google Analytics and look at the Language section, it shows 12% of my visitors are en-us. However geographically 100% of them are shown to be in the UK. Can anyone explain this to me? Thank you.

When you set up your computer you can specify whether you want en-uk (and therefore uk spellings) or en-us (american spellings). Can’t remember which is the default (probably depends on your computer manufacturer) but the 12% probably didn’t switch to en-uk or are americans now based in the uk.
Hope that helps.

Ah - I see - thank you so much!
