The strongest predictors of relationship status found were interactions between bi-nary variables for the age that a respondent first had sexual intercourse and for the age that a respondent first entered into a union (N = 1452). This paper con-cludes by arguing that the results provide support for viewing union status as being primarily dependent on the people involved in the union instead of being primarily dependent on factors external to the people themselves.展开更多
