Japan recently introduced a universal child benefit, but its life has been short lived mainly because of the Tsunami and financial problems as well as political conflict over the principles. Meanwhile the Coalition government in the UK, as part of its deficit reduction strategy, has frozen child benefit for three years and taken it back from higher rate tax payers. All other working age family benefits are being cut in real terms. In both countries, state support for families with children is in disarray. This article explores the evolution of the child benefit packages in both countries since 1992. It is based on model family analysis which enables comparison of policies to be made on a consistent basis. It reviews the consequences of these and other changes in the policy package for lone parent and couple families.
