Underrepresented is a term used to describe a group of people who are not represented proportionally to their population size in a given context.
For example, Black women are underrepresented on executive boards at fortune 500 companies because the percentage of Black women in the population is greater than the percentage Black women who sit on Fortune 500 boards.
Through recruitment programs and diversity and inclusion initiatives, organizations and systems can work towards representation, inclusion, and belonging for underrepresented groups in a given organization or system.
