This variable provides information on the level of response a person provided to the 'place of usual residence' question. Some people may provide an incomplete address of usual residence, and this flag indicates the geographic level at which imputation was then required. This variable can also be used to flag instances where people did not report their Usual Address Indicator Census Night (UAICP) and when it was possible to derive this indicator. For example, if a person was enumerated in Victoria and they provided a Tasmanian place of usual residence then UAICP is derived to 'Elsewhere in Australia'.
