The United States has the highest rate of remarriage in the world.
Many remarriages have children and, therefore, stepfamilies are created.
We have always had single parents and stepfamilies. This is not a new phenomena. Nevertheless, as the older word infers, the process in years past was one of loss to death not by choice. The history of divorce and remarriage is interesting to follow across time. In earlier times of Western civilization, marriage and divorce were more informal, personal decisions.
