Explanation:
Race
Narrow
Based on similar physical and biological attributes
Race is usually associated with biology and linked with physical characteristics, such as hair texture or skin color and covers a relatively narrow range of options. Yet people of similar complexions/hair textures can be defined as different races, and definitions in the United States have changed over time.
While some may be considered to be of a certain race, Black for example, people may identify more with their individual ethnicity, as opposed to race. This could apply for any member of any race.
Ethnicity
Broad
Based on cultural expression and place of origin
Ethnicity is a broader term than race. The term is used to categorize groups of people according to their cultural expression and identification.
Commonalities such as racial, national, tribal, religious, linguistic, or cultural origin may be used to describe someone’s ethnicity.
While someone may say their race is “Black,” their ethnicity might be Italian, or someone may say their race is "White," and their ethnicity is Irish.
