Most religions consider family life to be a blessing and value the stability of marriage. Christians believe the Church should be a model of family life.

There are various different types of family in the UK.

• Nuclear family - a family unit consisting of two adults and any number of children living together. The children might be biological, step or adopted.
• Extended family - grandparents, aunts, uncles, and cousins, either all living nearby or within the same household. For example, if a married couple lives with either the husband or wife's parents the family changes from a nuclear to extended household.
• Reconstituted family - also known as a blended family or step family. A family where one or both adults have children from previous relationships living with them.
• Single parent family - consists of a parent not living with a partner, who has most of the day-to-day responsibilities for raising the children. The children will live with this single parent for the majority of the time, but they may still have contact with their other parent.
• Same-sex family - since civil partnerships were legalised in 2005, the number of same sex families has been growing (same-sex marriage was legalised in 2014). Same-sex couples cannot conceive together, so their children may be adopted or be the biological children of one member of the couple. They may also be from a sperm donor or a surrogate birth mother.
