what is shanty town?

Shanty Town: Black South Africans in Johannesburg are so poor, and the city so overcrowded, that they are forced to live in a neighborhood built out of spare pieces of metal and other materials. No one knows what they will do when the winter comes. Shanty Town is an example of South Africans' inability to confront a problem. They build places where people can live right now, knowing that it can't last.
