Gentrification takes place in cities throughout the United States and other countries. It is the process of moving low income residents out, and replacing them with residents of a higher social class. Buildings and businesses in gentrified areas are also revamped. Gentrification is a controversial issue because while it improves cities and offers a brighter future, there are negative effects placed on displaced families who remain in poor living conditions just as before gentrification took place. Many also feel gentrification creates a new neighborhood and the old neighborhood is no more - when a neighborhood is gentrified it loses a bit of its history and a false, artificial neighborhood is created.
