Countries that Officially Speak an Indo-European Language
Really gives you an impression of how widespread these languages are. Enter countries that de jure, officially speak an Indo-European language.
Some countries, such as the USA and the UK, do not have an official language, so do not appear here.
I will not include regional languages or minority languages; it just takes too long to do.
I had to scour the web and use many, many sources. There was a lot of conflicting information. If there is a mistake, just tell me courteously in the comments.
You can't say something in the instructions an just not follow through. Mauritius, Mexico, Ethiopia, Australia, and Eritrea have no official languages. Also I didn't think Turkmen was an Indo-European Language, but I may be wrong on that.
