Gerrymandering is most likely a problem in what electoral system?

Question

Quizplus · Accepted Answer

Gerrymandering occurs when district boundaries are manipulated to favor one political party or group over another. In single-member systems, such as in the United States, each district elects only one representative, making it easier for politicians to manipulate the boundaries for political gain. In multi-member systems, proportional systems, and mixed-member systems, the need for more than one seat per district reduces the ability to gerrymander as easily.
