Additional notes and information

Many United Nations resolutions and reports use ‘early marriage’ and ‘child marriage’ interchangeably, without any noticeable distinction. Others use the phrase ‘early marriage, including child marriage’, implying that early marriage encompasses child marriage but also includes situations that do not qualify as child marriage, such as marriages in which one or both spouses are below the age of 18 but have attained majority under state laws.
