§ Mr. Berry
To ask the Secretary of State for Social Security how many, and what percentage of, children were in households with below half average income in each year from 1990 to 1999, calculated on the basis of the(a) Family Expenditure Survey and (b) Family Resources Survey, for Great Britain only, and on the basis of (i) equivalising and (ii) not equivalising net disposable household income. 
§ Mr. Bayley
The information requested on the basis of equivalised income is published annually in editions of Households Below Average Income, copies of which are in the Library. The latest available information relates to 1998–99.
Information is not available on the basis of not equivalising household income. Equivalising income is an inherent component of ranking households by income, for income distribution statistics such as those referred to here.
