One in five children across the UK is living in poverty, new figures suggest.
The End Child Poverty campaign, made up of more than 100 charities, has created a map of child poverty.
Among the poorest areas are central Manchester, west Belfast, north-east Glasgow, Tower Hamlets in London and Middlesbrough.
But many places have actually seen a slight improvement on poverty levels year-on-year.
Sheffield Hallam, Isles of Scilly and South Northamptonshire have the lowest levels of child poverty.
Enver Solomon, chair of End Child Poverty said: "Far too many children whose parents are struggling to make a living are having to go hungry and miss out on the essentials of a decent childhood that all young people should be entitled to."
The campaign is calling on authorities to prioritise poorer families when they decide on spending.
Child poverty is worked out by taking the 'median' (middle point) of UK wages - that's what people earn from working.
If the money made by a child's household is less than 60% of the 'median' then the child is considered to be living in poverty.
