Child marriages in the US

"In fact, more than 167,000 young people age 17 and under married in 38 states between 2000 and 2010, according to a search of available marriage license data by a group called Unchained at Last, which aims to ban child marriage. The search turned up cases of 12-year-old girls married in Alaska, Louisiana and South Carolina, while other states simply had categories of “14 and younger.” Unchained at Last was not able to get data for the other states. But it extrapolated that in the entire country, there were almost 250,000 child marriages between 2000 and 2010. Some backing for that estimate comes from the U.S. Census Bureau, which says that at least 57,800 Americans age 15 to 17 reported being in marriages in 2014."
