Forty percent of Americans have at least one steprelative in their family, either a stepparent, a stepsibling or half sibling, or a stepchild, according to the Pew Research Center.
根據皮尤調查中心的調查,40%的美國人在家中至少有一名繼親,比如繼父母、繼兄妹、半近親、或繼子等。
家庭中無血緣關係的姻親常用in-law來表示,比如father-in-law(岳父、公公);brother-in-law(內弟、妹夫)等。「同居伴侶」常稱為common-law partner,這類伴侶雖不構成法律婚姻,但在有些國家可構成de facto marriage/commom law marriage(事實婚姻)。
