Child marriage refers to the formal or informal union of a child, typically defined as someone under 18 years old, to an adult or another child. This practice is often rooted in cultural, economic, or religious beliefs and can have severe implications for the rights and well-being of the individuals involved, particularly girls, who are disproportionately affected. The issue raises critical questions regarding cultural norms and human rights, highlighting the tension between respecting cultural practices and protecting individual rights.
