Answer:
subordinate group
Explanation:
Subordinate group are a group of people that have lack of power within the society because they're being excluded by another group for lacking a certain characteristics.
Example of this would be African Americans in United States.
During the segregation period in 1930s, Black Americans were excluded from getting various government benefits simply from having "the wrong" color of skin. They did not have access to good education, job opportunities, government programs that can help sustain their economy, etc.
In the scenario above, the African Americans are considered to as Subordinate group while white Americans are considered the dominant group.
