What does family look like in Australia? It’s more diverse than you think

When we think of the concept of the family, a specific version often springs to mind: a mother, a father and children, usually two or three. It’s the version of society our policies and systems are built around.

But Australia’s families are far more diverse. Some are multigenerational, some are sole-parent, some are blended. We need to understand how families have evolved over time and what that means for the social fabric of our country.

Our new research, released today, charts years of data to map out what families have looked like historically and what they look like now. We also looked at how these families function, including income, wealth, labour division and care responsibilities.

Charting change over time

Families are the primary social environment in which we are cared for. As such, they play a fundamental role in our development and in making a thriving society.

Of the six million children and young people, aged 0–19 years, currently growing up in Australia, the majority learn and develop with the care and support of families. More than two and a half million families are raising children under the age of 15.

Our understanding of who counts as family has expanded enormously over the past 50 years. But too often, we assume families are nuclear. Research too is guilty of examining “families” without exploring variation. If any different forms of family are explored, they typically divide families into couple-parent and sole-parent families.

Shining a spotlight on family diversity is essential to ensuring that policies, systems and society are supportive and inclusive of the many ways children and young people grow up. We need to change the way we think about family.

Our team, in partnership with Uniting NSW.ACT, will report annually over the next decade to chart the diversity of families, how this changes over time, and the implications for policy and practice. Our first report analyses the 2022 wave of Housing Income and Dynamics in Australia (HILDA) data and the 2021 Census to examine these issues.

We found while the majority of children live in couple-parent (69%) and sole-parent (11%) families, 12% of children live in step/blended families, 6% live in multigenerational families, and around 1% live in foster families or families made up of other kin.

We also found First Nations families are more likely to live in multigenerational (9%), step and/or blended (27%), sole-parent (23%), or foster and other kin (6%) families.

Care, wealth and labour

Our analysis of ten years of the Census shows this diverse mix of families has been a consistent part of the Australian population over time.

As well as nurturing children and supporting young adults as they establish themselves in the world, we found families provide care during times of ill-health and disability. Unsurprisingly, multigenerational families are likely to provide this kind of care, because they are living with older adults with care needs.

But this was also the case for sole-parent families, step/blended families and foster and other kin families. All these family types are at least twice as likely to provide care than couple families.

We know the cost of living is affecting many families. However, our research suggests that couple families, on the whole, have higher incomes (around 1.5 times more) and higher levels of wealth, and are more likely to be able to cope with rising costs than other families.

Sole-parent families, step/blended families, multigenerational families and foster and other kin families have lower incomes and are more likely to experience financial hardship, with close to 20% reaching out to friends, family and community for financial help.

Across all family types, we found that old patterns around the gendered division of labour are still in force. Women continue to do more housework and more child-rearing than men. Women have this in common across all family types.
