What criterion defines a "people group" in the context of global demographics?

A "people group" is typically defined by a common affinity, which can encompass a variety of shared characteristics, including but not limited to culture, language, social customs, and historical experiences. This broad definition highlights the importance of subjective and social bonds among individuals who identify with one another. Common affinity allows for a more nuanced understanding of identity that goes beyond mere linguistic or national lines, recognizing that groups often share deeper social connections and collective experiences.

While language, nationality, and religious belief are significant factors in identifying and categorizing people groups, they alone do not capture the entire essence of the shared values and identities that bind individuals within a group. Thus, the concept of common affinity is vital for understanding complex demographic dynamics and intercultural relations within the context of global demographics.
