More than 200,000 children were married in the US over the past 15 years, new figures have revealed. The minimum age for marriage across most of the US is 18, but every state has exemptions - such as parental consent or pregnancy - which allow younger children to tie the knot. In May, the ... governor for New Jersey declined to sign into law a measure that would have made his state the first to ban child marriage without exception. At least 207,468 minors married in the US between 2000 and 2015, according to data compiled by Unchained At Last, a group campaigning to abolish child marriage. Eight-seven per cent of the minors who married across the country between 2000 and 2015 were girls, with the majority either 16 or 17. The youngest wedded were three 10-year-old girls in Tennessee who married men aged 24, 25 and 31 in 2001. The youngest groom was an 11-year-old who married a 27-year-old woman in the same state in 2006. Children as young as 12 were granted marriage licences in Alaska, Louisiana and South Carolina, while 11 other states allowed 13-year-olds to wed. More than 1,000 children aged 14 or under were granted marriage licences. Only 14 per cent of the children who wedded were married to other minors. In rare cases children were permitted to wed someone decades older. A 14-year-old girl married a 74-year-old man in Alabama, while a 17-year-old wed a 65-year-old groom in Idaho. Child brides usually come from poor backgrounds, said Dr Nicholas Syrett, author of American Child Bride.
