YOU CAN LEARN A LOT FROM a map. Who, for example, hasn’t asked themselves the burning question, “How many goats are there in the world, and where are they most dense?” Or who, perhaps while driving through middle America, hasn’t thought, “I wonder how many of these homes are actually meth labs?” And I know for a fact that every man in America has wondered if his state is home to the largest average penis size.

Fortunately, maps can answer all of these questions and more. Here are 23 maps that will teach you something about the world that you didn’t know before. Yes, you may not have needed to know some of these things, but learning is good for its own sake. Right?
