Health disparities (also called healthcare inequality in some countries) refer to gaps in the quality of health and health care across racial, ethnic, sexual orientation and socioeconomic groups.[1] The Health Resources and Services Administration defines health disparities as "population-specific differences in the presence of disease, health outcomes, or access to health care."
