Sorry for the click bait title - I'm assuming Afghanistan is not the 8th most used proper noun in German. However it's listed as such in what appears to be one of the most popular German frequency dictionary:
So this question is more out of curiosity about the Leipzig/BYU Corpus of Contemporary German. Can anyone comment on it? That Afghanistan should be listed as the 8th most used proper noun in German makes me wonder about the corpus and this dictionary that's based off it. That the DDR is listed as the 5th most used proper noun and Schröder as one of the most used names seems to point to it being less than contemporary (and not particularly broad).
I can't believe that even a corpus limited to just world news and the time around Peter Struck's famous quote back in 2004 that "Unsere Sicherheit wird nicht nur, aber auch am Hindukusch verteidigt" would yield such a high result for Afghanistan.
