Final answer:
The sociology term for 'fitting in' is assimilation, where a minority group adopts the characteristics of a dominant culture.
Step-by-step explanation:
A sociology term for 'fitting in' is assimilation. Assimilation is the process by which a minority individual or group gives up its own identity by taking on the characteristics of the dominant culture. This process can be observed within societies that have a history of welcoming immigrants from diverse backgrounds, where the newcomers adapt to the prevailing culture. It is important to note that assimilation is different from the 'salad bowl' metaphor associated with pluralism, where various cultures coexist without losing their unique identities. Assimilation often involves changes in socioeconomic status, spatial concentration, language skills, and patterns of intermarriage and can be challenged by racial and ethnic discrimination, which may hinder full assimilation.
