Gerrymandering in the United States by Congressional District

Gerrymandering takes place in many different districts in the country, however quantifying Gerrymandering is much more difficult. One way to calculate gerrymandering, called the Polsby-Popper method, includes a ratio of the area of the circle that circumscribes the district to the area of the district itself (McGlone).¹

Based on this definition, a “perfect” district would be a circle, but practically a perfect circle does not equal a perfect district. States that only have one district (Wyoming, Montana, North Dakota, South Dakota, Vermont, and Delaware in the contiguous United States) are considered perfect districts. Below is an informational diagram of representatives.
