While the numbers at home are nowhere near that dire, they are disturbing. Many of the children married between 2000 and 2010 were wed to adults significantly older than they were, the data shows. At least 31 percent were married to a spouse age 21 or older. (The actual number is probably higher, as some states did not provide spousal ages.) Some children were married at an age, or with a spousal age difference, that constitutes statutory rape under their state's laws. In Idaho, for example, someone 18 or older who has sex with a child under 16 can be charged with a felony and imprisoned for up to 25 years. Yet data from Idaho - which had the highest rate of child marriage of the states that provided data - shows that some 55 girls under 16 were married to men 18 or older between 2000 and 2010.
