Crowds in adolescence are groups of people your age who like to do similar activities or have similar beliefs or characteristics. For example, school age kids may create a crowd of people who like to play on the same sports team, people who listen to the same type of music, or classmates who have the same values or beliefs. Crowds can be made up of friends and peers who act together and make decisions together. Being a part of a crowd can help you discover new activities, music, and beliefs and help you fit in with people who are like you.
