Final answer:
The question on the level of ethnic pride among people in late adolescence and early adulthood does not have a definitive answer based on the information provided. Related research suggests a positive attitude towards one's own ethnicity and acceptance of others. Understanding this requires a look at broader sociocultural factors and personal experiences.
Step-by-step explanation:
The question does not provide enough information to conclusively answer how many people are proud of their ethnic background during late adolescence and early adulthood. However, based on related research, one can refer to findings on ethnic pride and identity. When it comes to ethnic pride and interethnic relations, for example, a newspaper article on dating and marriage showed that a high percentage of individuals from different ethnic groups would welcome members from other ethnic backgrounds into their families. This indicates a level of pride and acceptance of one's own and others' ethnicities.
Furthermore, it's important to note that individuals typically become aware of their sexual orientation in early adolescence, which can also be a formative time for the development of ethnic identity. Additionally, people generally feel that their current family is at least as close as the family they grew up with, suggesting strong family ties that may coincide with ethnic pride.
To understand the full context of ethnic pride during late adolescence and early adulthood, one should consider sociocultural influences, individual experiences, and the broader context of family and societal acceptance.
