What Does Ethnic Group Mean?

An ethnic group is basically a small part of the human population who very well closely relate to one and another. They can be united together based n terms like cultural, behavioral, linguistic and ritualistic or religious traits. It is also considered to be a cultural community. Results of such groups are also known as ethnogenesis.

While ethnicity and race are connected concepts the idea of ethnicity is entrenched in the thought of social groups, noticeable particularly by common nationality, tribal association, genealogy, religious faith, language, or cultural and traditional genesis, while race is ingrained in the thought of a biological categorization.

An ethnic group means (in simple words) people who had lived in an area a long time ago and do traditions, languages,and religion of their own.
