Notes on the data: Families

Single parent families with children aged less than 15 years, 2021


Policy context:  In the 2021 Census, of the families in Australia, 43.7% were couple families with children, 38.8% were couple families without children and 15.9% (1,068,268 families) were one parent families: 79.8% of single parents were female and 20.2% were male [1][2]. Compared with other family types, one parent families are considered to be at a higher risk of disadvantage, with respect to income, housing, employment and social participation [2].

The number of single parent families (increased by over 100,000 between 2016 and 2021, compared with an increase of 50,000 more families in 2016 when compared with 2011). As a result, many children spend at least some of their childhood with a lone parent; and many women and some men experience sole parenting, often in difficult financial circumstances. The economic and social wellbeing of one-parent families is a focus of social policy, as many single parent families also experience poorer health, and are major users of publicly-funded services. Details of their location are, therefore, relevant to policy makers and those providing health, education, welfare and housing and transport services.
