The family is the most important social group in all societies.
However, the family is changing. The extended (1-d) family is still the main type of family, although different types of small families are becoming more common, such as single-parent (2-c) families. In Britain about a quarter of all families with young children have only one parent, usually the mother. Over half of all UK marriages end in divorce (3-d), so many people marry again, creating new families. In some societies, the nuclear family is a part of larger, extended (4-b) family, which also includes grandparents and other relatives (5-c).
Traditionally, such families worked and lived together. The family educated the children and looked after the old people. In the West, the number of extended families has become smaller because people now often move to different places. Today, most people have jobs outside the family and children go to school. Friends and work colleagues are sometimes more important than family. Many people choose to be childless (6-a).
