Child

Biologically, a child (plural: children) is a human between the stages of birth and puberty. The legal definition of child generally refers to a minor, otherwise known as a person younger than the age of majority.

Child may also describe a relationship with a parent (such as sons and daughters of any age) or, metaphorically, an authority figure, or signify group membership in a clan, tribe, or religion; it can also signify being strongly affected by a specific time, place, or circumstance, as in "a child of nature" or "a child of the Sixties".

There are many social issues that affect children, such as childhood education, bullying, child poverty, dysfunctional families, child labor, and in developing countries, hunger. Children can be raised by parents, by fosterers, guardians or partially raised in a day care center.

Legal, biological, and social definitions

The United Nations Convention on the Rights of the Child defines child as "a human being below the age of 18 years unless under the law applicable to the child, majority is attained earlier". This is ratified by 192 of 194 member countries. In U.S. Immigration Law, a child refers to anyone who is under the age of 21.
