Raising a child in Britain costs an average of nearly £3,000 a year - or £50,000 from birth to the age of 17, according to the first results from a unique national study supported by the Joseph Rowntree Foundation.
It finds that parents provide 90 per cent of the spending on 'regular' items such as food, clothing, childcare, activities and holidays. But relatives, friends and older children themselves also contribute to the total, especially grandparents who provide an average of £115 a year for each child.
The study, based on a major survey of the lifestyles and living standards of more than 1,200 children, shows that even in low income families average spending on children is only slightly less than for children as a whole. Parents commonly prefer to sacrifice spending on themselves, rather than see their children go without.
Even so, the survey identifies one in ten children defined as 'poor' because their parents cannot afford at least three of the things that most other families take for granted - such as having three meals a day, sleeping in a bed of their own and wearing shoes bought new and properly fitted. One in thirty children are defined as 'severely poor' because they go without five or more of these necessities.
However, many more children would be deprived without the efforts that parents make to protect them from the worst effects of life on a low income. As many as 85 per cent of mothers say they sometimes go without clothes, shoes, holidays or their own entertainment in order to provide for their children. And one in 20 mothers sometimes go without food to ensure their children have enough to eat.
As a result, the survey found a notably higher proportion of parents who are poorer than their children. One in six are deprived of three or more items that a majority of adults consider essential - including one in 14 who go without five or more such necessities.
Children and state benefits
How the costs add up
Sue Middleton, a Research Fellow at the Centre for Research in Social Policy at Loughborough University and co-author of the study said: "Parents know from their own experience that bringing up children is expensive and demanding. But this study makes it clear that policy makers - especially those responsible for the tax and benefit systems - need to improve their understanding of what it costs to be a parent.
"Our survey findings suggest that the costs of younger children, in particular, are seriously under-estimated in benefit calculations. But they also raise the question of how far it is reasonable to expect low-income parents to make sacrifices on their own food and necessities in order to prevent their children from going without."
