Identity includes the details that describe who a person is. It can include a name, age, nationality, language, and interests. Some parts of identity are recorded in documents such as passports or school records.

A person may speak more than one language, belong to a sports team, or live in a particular country. These details are part of identity. Identity also includes group connections, such as culture or religion, as well as personal traits.

Identity begins forming in early childhood and can change over time. It is recognized in schools, communities, and legal systems.
