§ Mr. Marlow
asked the Chancellor of the Exchequer what proportion of earnings for a man on average earnings is available after tax and national insurance and with the addition of child benefit to (a) a single man, (b) a married man with one child and (c) a married man with two, three, four or five children, both in absolute terms and per head of members of the family.
§ Mr. Peter Rees
[pursuant to his reply, 15 May 1981, c. 373]: The figures for 1981–82, assuming the budget proposals are implemented, are as follows:
Net income (Net earnings plus child benefit, where appropriate) £/per week Net income as a proportion of gross earnings Per cent. Net income per head of members of family £/per week Single person 94.7 67.9 94.71 Married without children 99.16 71.1 49.58 Married with 1 child 103.91 74.5 34.64 Married with 2 children 108.66 77.9 27.16 Married with 3 children 113.41 81.4 22.68 Married with 4 children 118.16 84.8 19.69 married with 5 children 122.91 88.2 17.56
The estimated level of average earnings for January 1981 has been used—the latest month for which a figure is available. This figure—£139.40 per week—has been obtained by updating the figure in the new earnings survey for April 1980 of average earnings of full-time adult male workers taking account of the movements in a centred three-month moving average of the monthly index of average earnings of all employees covering the whole economy.
Net earnings are earnings after tax and national insurance contributions. National insurance contributions are at the not contracted out rate.
