Marginalized communities are groups of people who are socially excluded or disadvantaged and pushed to the fringes of society. They are often denied involvement in mainstream society and may lack the necessary influence to contest their marginalization. Examples of marginalized groups include women, people with disabilities, people of color, LGBTQ+ folks, Indigenous peoples, and people of lower socio-economic status. Marginalization can result from discrimination and can manifest as ignoring the needs of a specific group or failing to provide them with the same opportunities that are available to other members of society. Marginalization can have a cumulative impact on a population in many complex ways, including adverse life conditions and health outcomes. It is important to listen to marginalized groups directly as they share their needs and to work towards counteracting the effects of marginalization.
