Merriam-Webster gives us this definition:
ethnic: of or relating to large groups of people classed according to common racial, national, tribal, religious, linguistic, or cultural origin or background.
The graphic below might be helpful to illustrate an imaginative picture of an ethnic group. While the elements represented here may be significant parts of a person’s identity, from a cultural research perspective, one of these circles isn’t enough to claim ethnicity. You may consider yourself part of a particular religion, race, or even place. Those attributes, while important, need other factors for a cultural group to recognize “us” from “them.” It is at the juncture of several of these types of criteria that an ethnic group is held together.
See the definitions below for more about these attributes of ethnic groups.
