Children have paid the highest price in the recession, according to a report by Save the Children published today.
The charity says flat wages, cuts to benefits and the rising cost of living means that low-income families are being placed under a great strain.
One family from Merthyr told Save the Children about their struggle.
The family are waiting for the result of an appeal to change the benefits received by the father.
He now survives on £70 every fortnight in Employment and Support Allowance (ESA) since changes were made to his benefits.
The report highlights the so-called 'poverty premium' whereby those on the lowest income have to pay up to £1,939 each year for their goods and services because they don't have savings or access to cheap financing.
The Welsh Government says it's using resources across all government departments to tackle the problem.
Some of Wales' less well off parents are going without food so they can feed their children, according to a study by Save the Children.
The Welsh Government says one of its top priorities is to reduce poverty.
Krista Lane, from Cardiff, has benefited from one of the charity's schemes. The 'Eat, Sleep, Learn, Play' programme provided her with a chest of drawers for her son and educational toys for her daughter.
"Electric... gas... sometimes I'd run out and I'd have to ask family members to help. It was really hard" she says.
James Pritchard, Head of Wales for Save the Children, says single mothers will bear the brunt of the UK Government's welfare reforms.
