About sponsorship Poverty line Head count Jun 15th 2006 From The Economist print edition The devil in the details HOW many children are poor? Working it out entails four main steps. First, net household income is calculated by deducting direct taxes, such as income tax, from earnings, benefits and tax credits. Second, net income is “equivalised?to put households, which vary in size and composition and by age of children, on a common footing that is expressed in terms of a childless couple. A two-parent family with two children aged 13 and 14, for example, needs 54% more income than a childless couple in order to have the same standard of living. The third step is to calculate the median household annual income, which divides the whole population, when ranked by equivalised income, into two halves.

The number of poor children varies a lot according to where precisely the poverty line is drawn. On the usual definition, 24% of children were poor in 1998-99. But if the poverty line were set at 50% rather than 60% of median income, the child-poverty rate would have been 13%. Child poverty can be measured before or after housing costs.
