Traditional family has been defined as two or more people who are related by blood, marriage, and—occasionally—adoption (Murdock, 1949).
Research from the US (Harris, 2015) and Japan (Veldkamp, 2009) finds that many pet owners consider their pets to be members of the family.
Another traditional form of family is the joint family, in which three or more generations of blood relatives live in a single household or compound.
Common to each of these family forms is commitment, caring, and close emotional ties—which are increasingly the defining characteristics of family (Benokraitis, 2015).
The changing definition of family has come about, in part, because of factors such as divorce and re-marriage.
Historically, the most standard version of the traditional family has been the two-parent family.
