Family denotes a group of people affiliated by consanguinity, affinity, or co-residence. Although the concept of consanguinity originally referred to relations by "blood," many anthropologists have argued that one must understand the notion of "blood" metaphorically, and that many societies understand 'family' through other concepts rather than through genetic distance.
Many sociologists and anthropologists believe the primary function of the family is to perpetuate society, either biologically, socially, or both. Thus, one's experience of one's family shifts over time. From the perspective of children, the family is a family of orientation: the family serves to locate children socially, and plays a major role in their enculturation and socialization. From the point of view of the parent(s), the family is a family of procreation the goal of which is to produce and enculturate and socialize children. However, producing children is not the only function of the family; in societies with a sexual division of labor, marriage, and the resulting relationship between two people, is necessary for the formation of an economically productive household.
A conjugal family consists of one or more mothers and their children, and/or one or more spouses, usually husbands. The most common form of this family in the western world is regularly referred to as a nuclear family.
