Idaho state in United States of America does not have minimum age for men and women who want to get married. In fact, a total of 13 states in the US do not have minimum marriage age as of Sep 2019.
This is a great shame and it is ironical that the US federal government considers marriage below age 18 a human rights issue.
California too does not have a minimum marriage age. Elsewhere in New Hampshire, the minimum marriage age is 14 .
