In the context of global population ageing, the reconciliation of employment and unpaid caring is becoming an important social issue. The estimation of the public expenditure costs of carers leaving employment is a valuable measure that is of considerable interest to policy makers. In 2012, the Personal Social Services Research Unit estimated that the public expenditure costs of unpaid carers leaving employment in England were approximately £1.3 billion a year, based on the costs of Carer's Allowance and lost tax revenues on forgone incomes.
