In the past many families were similar, as traditional nuclear families were the excepted norm of society. Since the 1970's a number of major changes have taken place in family life. The traditional nuclear family is no longer seen as the norm as many other types of specialist families have developed to best suit the needs of the people within them. Family life is very complex and in recent years sociologists have sort to find new ways to understand it. However with these changes there have also been a number of concerns, which may suggest that not all changes have improved family life.
One way in which the family unit has changed since the 1970's is the change in marriage rates. While marriage in the UK is still the majority among families, there has been a decline in the number of marriages, the age in which people are choosing to marry and the duration of marriages. In 1971 1% of all marriages in the UK ended after two years. In 1996 this figure increased to 9%. (Mark Kirby, 2000, p. 58). This suggests that marriage less important than it once was. There are a number for reasons as to why there is a change in marriage. It is argued that because women now have more freedom of choice than they did in the past, they may be choosing simply not to marry. Others suggest that women are now choosing to put off marriage till a later date so that they can focus on their careers and education. Another reason for the change in marriage could be due to the undermining of the need to marry, now that it has become socially acceptable to cohabit or be single, many people choose not to marry. As well as this women are no longer dependant on men to be a 'bread winner' and provide for them. Lorraine Harding (1996) argues that the main decline in marriage occurred around the 1970's due to greater levels of unemployment. Strain may have been
