NUMBER OF HOUSEHOLDS
The number of households in Australia is projected to increase from 8.4 million in 2011 to between 12.6 and 12.7 million in 2036 (Series III and Series I respectively). This is an increase of between 4.2 and 4.3 million households, or 49% to 51%. Over the same period, Australia's population is projected to increase by 45%, from 22.3 million people to 32.4 million people. The average household size in Australia was 2.6 people per household in 2011, and is projected to be between 2.5 and 2.6 people per household in 2036.
Family households are projected to have the largest increase over the projection period, remaining as the most common household type in Australia. The number of family households is projected to increase by between 2.7 and 2.8 million households, from 6.0 million in 2011 to between 8.7 and 8.8 million in 2031. Family households can contain more than one family. In 2011, 2.3% of all family households in Australia were multiple family households. Assuming this proportion remains constant between 2011 and 2036, the number of multiple family households would increase by between 65,800 and 68,300 households, from 144,200 in 2011 to between 210,000 (Series III) and 212,500 (Series I) households in 2036.
LONE PERSON HOUSEHOLDS
Although family households show the greatest numeric increase, lone person households are projected to show the greatest percentage increase over the 25-year projection period. The number of lone person households is projected to increase by between 61% and 65% (1.3 million households), from 2.1 million households in 2011 to between 3.3 million and 3.4 million households in 2036. This increase primarily reflects changes in the age structure of the population and the fact that older women in particular are more inclined to be living alone than other people.
The number of group households in Australia is projected to increase from 367,900 in 2011 to between 504,000 and 527,200 in 2036. This is an increase of between 136,100 and 159,200 households, or 37% to 43%, over the projection period. As a proportion, group households made up 4.4% of all households in Australia in 2011 and are projected to decrease to between 4.0% and 4.2% by 2036.
The projected average annual growth rate in the number of households in Australia for the period 2011 to 2021 (1.8%) is higher than the projected rates for New Zealand (1.2%), England (1.0%), Scotland (0.7%) and Japan (0.2%). Average household size is projected to decline for all of the selected countries between 2011 and 2021, and Australia average household size is projected to remain the largest of these countries.
