What are the characteristics of an involuntary group?

Involuntary groups are characterized by membership that is not chosen by individuals but is instead imposed by external factors, such as legal, social, or economic circumstances. Members of these groups often share common traits, such as ethnicity, nationality, or socio-economic status, and may have limited control over their association. Examples include prisoners, refugees, or individuals living in certain communities. The dynamics within involuntary groups can be influenced by the lack of agency and the shared experiences of their members.
