[holding answer 3 December 1998]: The table shows estimated average gains arising from the introduction of Working Families Tax Credit for those eligible for the credit. The overall average gain including childcare costs is estimated to be £17.20 per week. Individual decile gains do not include gains arising from the changes to the treatment of childcare costs in Working Families Tax Credit or other behavioural changes arising from the introduction of the credit, as they can not be reliably apportioned across deciles.

Deciles are defined in terms of equivalised income on a benefit unit and household income basis using the McClements scale; decile boundaries are higher for households than benefit units.
These estimates have been derived from projections of Family Expenditure Survey data to 1999–2000
