All left-handed people in the United States would be classified as a <u>category</u>.
In the discipline of sociology, there are various ways in which people are classified. These include classes like category, crowd, aggregate, and group.
A category encompasses people who share certain characteristics. But they do not necessarily interact or share connections with one another. For example, adolescents. A crowd consists of a large number of people who gather together for some purpose. For example, a Christmas crowd.
Aggregates include people who happen to share a space but do not have a sense of belongingness. For example, people in a mall. A group consists of people who see themselves as belonging together and sharing an identity and norms. For example, a religious community.
