|Imputation Flag for Number of Males and Females in Dwelling (IFNMFD)This variable indicates whether the number of males and females could be established for an occupied private dwelling, or needed to be imputed.|
Most occupied private dwellings (96.5%) return a completed form so the number of persons, by sex, is known. For 1.2% of occupied private dwellings the Collector was able to obtain a count of males and females even though a completed form was not received. The number of males and females was imputed for the remaining 2.3% of occupied private dwellings.
For the purposes of imputation the count of males and females should be a 'Census Night count' (that is, a count of persons staying at the dwelling on Census Night). However the count provided to the Collector may on occasions be a 'Usual resident count' (that is, a count of persons who usually reside in the dwelling). This may result in a small overcount in cases where usual residents are temporarily absent on Census Night and enumerated elsewhere, and to a lesser extent, an undercount if there were visitors staying at the dwelling on Census Night.
More information is available from the 2011 Census non-response quality statement.
