Which best defines an ethnic group?

An ethnic group is best defined by similarities in cultural practices, which include shared language, traditions, customs, and values that connect individuals within that group. Members of an ethnic group often have a common sense of identity and belonging that is derived from their shared cultural heritage. This cultural aspect can encompass various elements such as religion, social norms, and historical narratives that contribute to the group's unique identity.

In contrast, definitions based solely on geographical location or political affiliations focus on external factors rather than the intrinsic cultural connections that define an ethnic group. Additionally, grouping individuals based solely on biological traits can lead to the misconception of race, which is a social construct rather than a purely biological distinction. Understanding ethnic groups in terms of cultural practices highlights the importance of shared experiences and histories among individuals, fostering a sense of community and belonging.
