Indigenous and Other Australian Poverty : Revisiting the Importance of Equivalence Scales

Equivalence scales attempt to control for family size and composition, as well as the relative costs of maintaining various family types.

The main finding is that the assumptions about the costs of children can increase Indigenous poverty by a factor of two-and-a-half. Another finding is that the choice of equivalence scales can induce large threshold effects that influence the composition of poverty
