A gang is a group of people who do things together. The word "gang" comes from the Old English gan, which means "to go". It is also related to Old Norse gangr "a group of men".[1] In modern times the word gang is often used to refer to a group of people who commit crimes together. Members of criminal gangs may be called gangsters.
There are several reasons why people join gangs. Lots of people who join gangs are young people. One reason that people join gangs is a chance to make money through doing things like selling illegal drugs, stealing and sex trafficking. Another reason, especially for younger people, is a chance to have a place where they belong. A third reason is boredom.[2]
