What do we call the range of different people, cultures, and ideas in a group?

The term that describes the range of different people, cultures, and ideas in a group is diversity. This concept encompasses the unique characteristics and perspectives that individuals bring, which can include variations in ethnicity, gender, age, sexual orientation, socio-economic status, and more. Diversity is important because it enriches communities and workplaces by fostering innovation and understanding through a variety of viewpoints and experiences.

The other options relate to different contexts: joint custody pertains to the shared responsibility of raising children after a separation or divorce, alcoholism refers to a compulsive drinking disorder, and neglect is a form of maltreatment where someone fails to provide necessary care. These concepts do not address the broader social and cultural aspects that define diversity.
