Do other countries have a similar variety of dialects as Germany?
This might be a quite naive question but I only know 3 languages, Polish, German and English. I am asking this because I am Polish by blood but more German as I grew up here but I noticed there are way more dialects in Germany then in Poland where the language is quite homogeneous. Sure there are the Silasians and Górals but other than that there is not much variety. The UK seems to be quite similar with a lot of regional dialects.
So the question goes out to all migrants, Germans with a background and Germans who live abroad. How big is the variety of dialects (not different languages though!) in other countries? Is it even more diverse than in Germany or less?
