Final answer:
Ethnicity is focused on shared culture and practices like language and religion, rather than physical attributes like race does. Ethnicity and race are distinct yet important concepts for personal identity and societal dynamics while minority groups refer to subordinate groups lacking societal power.
Step-by-step explanation:
Ethnicity as a category focuses on culture rather than physical differences. This concept is based on shared cultural characteristics, such as language, religion and traditions among other things. The distinction between ethnicity and race is essential to understand as race is often related to physical attributes while ethnicity is connected to shared cultural practices and history.
Both race and ethnicity are important in understanding the dynamics within societies, and they play a significant role in personal identity as well as in various institutional contexts like the census and non-discrimination laws. Moreover the concept of minority groups transcends both ethnicity and race, focusing instead on the power dynamics within a society, thereby describing groups that are subordinate or that lack power irrespective of their skin color or country of origin.
