Dange of A Single Story

What does it mean to have a single story about a place or community? For me  A single story is like the saying''Dont judge and book by its cover.Some People say that Africa is a poor place with nothing but poverty. But Africa is a very beautiful place with many animals and great places to see and meet people. Describe a single story you have heard told about your community. What is missing from that story? How could people learn more about that community?
