Diversity refers to the differences between people in a group or society. These differences can include language, culture, religion, and appearance. Diversity is found in many places around the world.

In some countries, such as India or Papua New Guinea, hundreds of languages are spoken. A classroom may include students with different backgrounds, traditions, and experiences. Diversity can include both visible traits and less visible ones such as beliefs or abilities.

Diversity is recognized in communities, schools, and workplaces. It is often described using population data and social information.
