Census year intervals are irregular, with the 2006-2013 an exception to the usual 5-yearly census.
The census did not ask respondents about family trusts prior to 2006. Ownership figures for 2006 and 2013 include households whose home was held in a family trust.

Many people consider home ownership to be a goal, providing personal independence as well as stability and security for their families and a form of savings for retirement.
