Here's a breakdown:
* Legal Definition: This varies widely from place to place. In some countries, the age of majority (when a person is legally considered an adult) is 18, while in others it's 21. The age of majority is often the same as the age at which individuals can vote, enter into contracts, and make legal decisions for themselves.
* Social Definition: The term "juvenile" is often used to refer to individuals who are still in their youth or adolescence, even if they've reached the legal age of majority.
* Contextual Definition: The meaning of "juveniles" can also be shaped by the context. In criminal justice, for instance, it usually refers to people under the age of 18 who have committed a crime.
It's crucial to note that the term "juvenile" can carry negative connotations and can be considered outdated or stigmatizing in some contexts. The use of more neutral terms like "youth" or "adolescents" is generally preferred in modern discourse.
