In the 2000 U.S. Census, 33% of female same-sex couple households and 22% of male same-sex couple households reported at least one child under eighteen living in their home. Some children do not know they have an LGBT parent; coming out issues vary and some parents may never come out to their children. Adoption by LGBT couples and LGBT parenting in general may be controversial in some countries. In January 2008, the European Court of Human Rights ruled that same-sex couples have the right to adopt a child. In the U.S., LGBT people can legally adopt, as individuals, in all fifty states.
