There are more lone-parent families and more couples, both straight and gay, now cohabit, many more children are born outside marriage than previously, and many more marriages end in divorce
See modern society as having a fairly fixed, clear-cut and predictable structure, with the nuclear family as the 'best' family type that slots into this structure and helps to maintain it
The nuclear family is uniquely suited to meeting the needs of modern society for a geographically and socially mobile workforce, and performs two 'irreducible functions' - the primary socialisation of children and the stabilisation of adult personalities

The New Right see the traditional nuclear family as 'natural' and based on fundamental biological differences between men and women, and as the cornerstone of society
The New Right oppose changes in family patterns such as cohabitation, gay marriage and lone parenthood, and argue that the decline of the traditional nuclear family and the growth of family diversity are the cause of many social problems
