Primary Theme: Information, Society & Culture

Gerrymandering has been increasingly used to undermine the Democratic process. Although there remains no standard to detect partisan gerrymandering, we have begun to develop promising and potentially justiciable techniques. These techniques expose the natural geopolitical structure of a region, and understanding this structure can be used to identify political and racial gerrymandering.
