Explanation:

To understand the context of the question, let's understand the concept of dominant groups and non-dominant groups.

Dominant groups are those formed by a social group that has the most control over benefits and value in a given locality, which has the highest social status, power and privileges.

Thenon-dominant groups are those whose benefits and privileges are opposed to those of the dominant group, that is, this non-dominant social group does not have the same opportunities and benefits, but lack control and power in a society.

This is a sociological phenomenon that can be identified through several variables, the most relevant being the infrastructure of a given society, the conditions of employability, and the identifiability of social groups that have more privileges than other groups, and what are the main reasons for difference.

These factors are important for greater identification and implementation of public policies that promote the inclusion of conditions similar to less privileged individuals.
