Families vary in their structures, the ways they organise their domestic division of labour and their social networks such as their links to their extended family
Families differ in their cultural values and beliefs. Different ethnic groups have themes of South Asian and Caribbean heritage that create diversity in beliefs and values. These different beliefs and values can affect people's lifestyles and ideas about gender roles, child-rearing, education and paid work
A family's social class position affects the resources available to its members, role relationships between parents, and child-rearing practices such as how parents discipline their children
The stage in the family life-cycle that a particular family has reached. Newlyweds without children, families with young children and retired couples in empty nest families are all at different stages in the life-cycle and have different lifestyles
The particular period of time in which a family passes through different stages of the family life-cycle. For example, over time divorce has lost its social stigma, so younger couples may find it easier to get divorced today

During the early 20th century, married women were responsible for domestic labour and men were the main wage earners
Parsons (1956) argued the man takes the more instrumental role as breadwinner, the woman takes the more expressive role as housewife and mother, explained in terms of biological differences
The wider family is becoming less important and family ties are weakening
Young and Willmott (1957) found that the extended family flourished in Bethnal Green in London during the mid-1950s and family ties were strong, but in later research they discovered that the nuclear family had become more isolated from the extended family
Increasing geographical mobility and women's involvement in full-time paid work mean that family members see each other less often
Geographical distance affects the type of support between family members but does not eliminate it altogether, as support at a distance takes the form of visits, phone calls and financial help
