Final answer:
Segregation based on informal norms is known as de facto segregation. Cultural pluralism refers to the coexistence of different ethnic and cultural groups within a society.
Step-by-step explanation:
Segregation based on informal norms is known as de facto segregation. This type of segregation occurs without legal requirements or policies, but rather as a result of societal attitudes and practices.
For example, in the United States, de facto segregation was prominent in the Jim Crow era, where African Americans faced widespread discrimination and were socially excluded from many public spaces.
Cultural pluralism refers to the coexistence of different ethnic and cultural groups within a society, allowing for diversity and the expression of multiple identities.
