Family Income Derivation Indicator
| Family Income Derivation Indicator (FIDF)This variable identifies families where one or more family members were temporarily absent, did not state their income, or stated a negative income. Family Income Derivation Indicator (FIDF) can also be used to estimate the impact on total family income caused by negative/no income or persons temporarily absent. FIDF is derived from a number of other variables including Family Composition (FMCF) and Total Personal Income (INCP). It also uses the Count of Persons/Dependent Children Temporarily Absent from Family variables (CPAF / CDCAF) to isolate families with members aged 15 and over temporarily absent on Census Night. FIDF can be used to estimate the impact on total family income caused by negative/no income or persons temporarily absent. For further information see the data quality statements for Family Composition (FMCF) and Total Personal Income (INCP). More information on FIDF is available in the 2011 Census Dictionary (cat. no. 2901.0). Back to Family classification |
