Embargoed until 10:45am  –  08 December 2008
Highlights

The following highlights are based on series 5B, which assumes medium fertility, medium mortality, long-term annual net migration of 10,000 and 'B' living arrangement type rates (see the 'Commentary' section for more detail):

  • Most of the growth in families will be in couple without children families, which will overtake two-parent families to become the most common family type by 2008.
  • The number of households is projected to reach 2.09 million by 2031, an increase of 535,000 (34 percent) from an estimated 1.55 million households at 30 June 2006.
  • One-person households are projected to increase by 71 percent, from 363,000 in 2006 to 619,000 in 2031.
  • The average size of households will decrease to 2.4 people by 2031, from 2.6 people in 2006.
  • The numbers of families and households will grow faster than the population, which is projected to increase by 22 percent between 2006 and 2031.
