Cultural diversity is the quality of diverse or different cultures, as opposed to monoculture. It has a variety of meanings in different contexts, sometimes applying to cultural products like art works in museums or entertainment available online, and sometimes applying to the variety of human cultures or traditions in a specific region, or in the world as a whole. It can also refer to the inclusion of different cultural perspectives in an organization or society.
Cultural diversity can be affected by political factors such as censorship or the protection of the rights of artists, and by economic factors such as free trade or protectionism in the market for cultural goods. Since the middle of the 20th century, there has been a concerted international effort to protect cultural diversity, involving the United Nations Educational, Scientific and Cultural Organization (UNESCO) and its member states. This involves action at international, national, and local levels. Cultural diversity can also be promoted by individual citizens in the ways they choose to express or experience culture.
