Which gangs are primarily located in the Midwest?

The Gangster Disciples and Vice Lords are two prominent gangs that have established a significant presence in the Midwest, particularly in urban areas such as Chicago. This region has historically been a stronghold for these gangs due to various social, economic, and historical factors. The Gangster Disciples originated in the Chicago area during the late 1960s and have since expanded their influence throughout the Midwest, engaging in various criminal activities. Similarly, the Vice Lords, one of the oldest gangs in Chicago, have also maintained a strong presence in the region.

In comparison, while the Crips and Bloods have a nationwide presence and are particularly associated with the West Coast, they are not predominantly located in the Midwest. Other options, such as the inclusion of Hispanic gangs, may be relevant in some contexts but do not specifically address the main gangs that dominate the Midwest landscape. Thus, recognizing the influence and established history of the Gangster Disciples and Vice Lords in the Midwest directly supports the choice of this answer as the correct one.
