Family type, 2011

According to the 2011 Census, there were 5,584,000 families in Australia. Most of these families represented couples without children (37.8%) and couples with dependent children (36.7%). One-parent families with dependent children accounted for 10.6% of all families. The remainder were couples with non-dependent children only (representing 7.9% of all families), one-parent families with non-dependent children only (representing 5.3% of all families), and "other families" (1.7%).
| Family type | No. families | % |
|---|---|---|
| Couple with dependent children | 2,086,269 | 36.7 |
| Couple with non-dependent children only | 448,133 | 7.9 |
| Couple only | 2,150,299 | 37.8 |
| One parent family with dependent children | 600,892 | 10.6 |
| One parent family with non-dependent children only | 300,748 | 5.3 |
| Other families | 97,721 | 1.7 |

Family type, 1976-2011

From 1976 to 2011:
- the proportions of couple families without children and one parent families with dependent children have increased;
- The proportion of couple families with children decreased—a trend that applied to both those with dependent children and those with non-dependent children only.
| Family type | 1976 | 1986 | 1996 | 2006 | 2011 |
|---|---|---|---|---|---|
| One parent family with dependent children | 6.5 | 7.8 | 9.9 | 10.7 | 10.6 |
| Couple only | 28.0 | 30.3 | 34.1 | 37.2 | 37.8 |
| Couple with dependent children | 48.4 | 44.8 | 40.6 | 37.0 | 36.7 |
| Couple with non-dependent children | 11.1 | 10.9 | 9.0 | 8.3 | 7.9 |
| Other families | 5.9 | 6.2 | 6.4 | 6.8 | 7.0 |

Families with children 0-17 years, 2009-10

In 2009-10, there were 2,656,000 families with children under 18 years. The majority of these families were intact families. Step and blended families accounted for less than 8%. Nearly one in five families was headed by only one parent. One-parent families were typically headed by single mothers.
| Family type | No. families ('000) | % |
|---|---|---|
| Intact families | 1933 | 72.8 |
| Step families | 99 | 3.7 |
| Blended families | 91 | 3.4 |

Family type projection 2006-2031
According to ABS "Series II" projections:
- the proportion of couple families with children will decrease while the proportion of couple families without children will increase;
- couple families without children will outnumber couple families with children from 2014;
- the proportion of one parent families will change little.

ABS released household and family projection (2006-2031) in 2010. There are three projection series with different assumptions: a) living arrangement propensities for 2006 continues to 2031; b) low rate of change in living arrangement propensities; c) the linear trend in the rate of change in propensities from 1991 to 2006 continues to 2031 (for details see ABS (2010) Household and family projects, Australia, 2006 to 2031). The figure is based on the assumptions of low rate of change in propensities ( Series B projections):
- the proportion of couple families with children will decrease while the proportion of couple families without children will increase;
- couple families without children will outnumber couple families with children from 2014;
- the proportion of one parent families will change little.

Note: The percentages are based on the Series B projections. ABS Series B projections are based on the assumption of low rate of change in propensities - the linear trend in propensities from 1991 to 2006 continues at the full rate of change to 2011, half the rate change to 2016, one-quarter the rate of change to 2021, and then remains constant to 2031.
