Different categories of social welfare recipients have differing needs. The social welfare system must be flexible enough to respond adequately to these needs. The different methods of assessing earnings as between the various social welfare payment schemes and as between different household situations reflects specific policies which are aimed at targeting particular groups of recipients for special attention.
It should be noted that the two household situations described in the question are not similar. One relates to a household where there is a single earner only, while the other relates to a household where the income is provided by two people.
In relation to the one-parent family payment, which was introduced earlier this year, research carried out by the ESRI has clearly shown that one-parent families are particularly at risk of poverty and social exclusion. Under this scheme, a lone parent can earn up to £6,000 a year without affecting his-her entitlement to payment. This measure is aimed at facilitating lone parents who wish to return to the workforce, by providing positive support so that, over time, they can gain a foothold in the labour market and become less reliant on social welfare for their income needs.
The £60 earnings threshold is one of a number of different methods which are used to determine whether a claimant's spouse is to be regarded a financial dependant for qualified adult allowance purposes. Where the spouse of a claimant is adjudged to be financially dependent, then the allowance, together with full child dependant allowances are paid to the claimant, in addition to his or her personal rate of payment. Where the spouse is not regarded as a dependant, then the allowance is not payable and only half of the child dependant allowances are payable.
However, the sudden withdrawal of the qualified adult allowance and half of the child dependant allowances where the income of the spouse of a claimant exceeds £60 a week creates a sharp poverty trap. The national agreement: "Partnership 2000" provides that "measures to alleviate this poverty trap will be considered, in consultation with the social partners".
