A classified subset of people, usually nested within a pre-existing minority group ad infinitum, or made of intersections of minority classifications. Often found to parasitize or symbiotically coexist within a larger minority group in service to their own smaller group goals, delegation of resources, management of attention, self-identification, and core niché issues. Fractal patterns define the term visually.
"Jane and I are African Americans in the USA, so we are minorities. However, Jane is also non-binary and disabled, making her also a 'micronority' with her own smaller subset of valid needs and issues."
