A minority is a group of people who because of their physical characteristics are singled out and unequally treated

Explanation:

Minorities are marginalized groups within a society due to economic, social, cultural, physical or religious aspects. In the twentieth century, the most well-known case of minority persecution occurred in Germany at the time Adolf Hitler took power. In this period, the Nazi party imprisoned and exterminated millions of Jews with the justification that they were not part of the Aryan biological and racial superiority. Among other groups, the Nazis persecuted Communists and Gypsies, which is the reaction against minorities not only religious but ideological and social.

However, the term should not be associated with smaller numbers in a society, but rather with the control of a majority group over the others, regardless of the numerical quantity.
