In the process of setting electoral districts, gerrymandering is a practice that attempts to establish a political advantage for a particular party or group by manipulating geographic boundaries to create partisan or incumbent-protected districts. The resulting district is known as a gerrymander.
Gerrymandering may be used to achieve desired electoral results for a particular party, or may be used to help or hinder a particular demographic, such as a political, ethnic, racial, linguistic, religious, or class group.
Computer models can handle these tasks to eliminate political advantage.
