Usual Address One Year Ago Indicator (UAI1P)

This variable records whether a person lived in the same address one year ago as their current usual residence, whether they lived elsewhere in Australia one year ago, or whether they usually lived in another country one year ago. It is applicable for all usual residents of Australia, except for persons aged less than one year.

The question relating to The Usual Address One Year Ago Indicator (UAI1P) was first asked in the 1976 Census. Further information on Census Topics 1911–2011, can be found in How Australia Takes a Census (cat. no. 2903.0).

The non-response rate for this variable was 5.1% in 2011 (7.4% in 2006). More information is available from the 2011 Census non-response quality statement.

The responses to this question are captured automatically from mark box responses on the form so the risk of processing error is minimal. Sample checks are undertaken to ensure an acceptable level of quality. Where the indicator mark boxes have been left blank by a respondent but they have reported an address one year ago, UAI1P is derived based on the address reported. If the respondent does not report either the indicator or the address, they will be set to not stated. However, where a person who is aged under 16 years (i.e. they were aged under 15 one year ago) does not respond to the usual address one year ago question, but their parent(s) did respond, their UAI1P is set to the same value as their parent.

For Interviewer Household Forms (IHF), primarily used in discrete Aboriginal and Torres Strait Islander communities, the response options on the form are different. Instead of asking if respondents lived in their place of usual residence one year ago, the form asks if people lived in 'this dwelling' (i.e. the dwelling in which they were enumerated), elsewhere in the community, or elsewhere in Australia. The data is re-derived to ensure that the data is comparable to those enumerated using other form types. For IHFs, mobility is considered at the community level rather than at the individual dwelling level.

More information on UAI1P is available in the 2011 Census Dictionary (cat. no. 2901.0).
