NEW YORK (AP) — Facebook has added civil unions and domestic partnerships to the list of relationships that its users can pick from to best describe their romantic status.

The world's largest online social network also gives its users the option to list themselves as single, married, in an open relationship or "it's complicated," among others.

The option for civil unions or domestic partnerships is only available to Facebook users in the U.S., Canada, the U.K., France and Australia, says the nonprofit Gay & Lesbian Alliance Against Defamation, which has been among the groups working with Facebook to add the options.
