Family Income Derivation Indicator (FIDF)
Family Income Derivation Indicator (FIDF) identifies families where one or more family members were temporarily absent, did not state their income, or stated a negative income.
FIDF can also be used to estimate the impact on total family income caused by negative/no income or persons temporarily absent.
Family Income Derivation Indicator (FIDF) can be used in conjunction with Individual Income (INCP) to create a new family income variable.
