Badger.org lists several species of badgers that live in different parts of the world, but Wikipedia states that there are only three subfamilies. These subfamilies draw lines between the European, American and African honey badgers.
According to Wikipedia, the European badgers have the widest range by far. These hardy creatures live in nearly every European country, and their range extends to parts of Asia as well. Wikipedia lists every country the European badger calls home. These countries are Afghanistan, Austria, Albania, Bosnia, Belgium, Bulgaria, China, Crete, Croatia, Czech Republic, Denmark, Estonia, France, Finland, Great Britain, Germany, Greece, Hungary, Herzegovina, Italy, Ireland, Iraq, Iran, Israel, Lithuania, Latvia, Luxembourg, Moldova, Macedonia, Montenegro, Netherlands, Norway, Portugal, Poland, Russia, Romania, Slovakia, Slovenia, Spain, Serbia, Switzerland, Sweden and the Ukraine.
Wikipedia states that the honey badger has the second-widest range among the three badger subfamilies, though it's the only one not considered a true badger like its American and European relatives. The honey badger lives in Turkmenistan, the Indian Peninsula, Iran, Arabia, some parts of western Asia and nearly every country in sub-Saharan Africa. On the other hand, the American badger has a much smaller range and only lives in the United States, south-central Canada and northern Mexico.
