An underrepresented minority group is a national or ethnic, religious and linguistic minority group, who make up a smaller percentage within the general population.

Minority group also refers to a category of people who experience relative disadvantage as compared to members of a dominant social group, for example in their social life, including housing, employment, healthcare, and education, among others.

In Australia, this could include migrants, refugees, Aboriginal and Torres Strait Islanders people, those who identify as LGBTI or people with accessibility needs.
