MP Michael Dugher has slammed the Government for creating a Northern Poor House - not a Northern Powerhouse.
New figures reveal that more than one in five neighbourhoods in the Barnsley Local Authority area are among the most deprived in England.
The 2015 Index of Multiple Deprivation figures show that of the 143 neighbourhoods across the local authority area, 32 are ranked in the top 10 per cent of most deprived neighbourhoods.
Mr Dugher said: "With more than one in five neighbourhoods in Barnsley among the most deprived in England, we are a world away from the Government’s so-called ‘Northern Powerhouse’.
“We need to support people in Barnsley and increase social mobility, but this Government is hitting families with a tax credit cut that will see over 5,000 working families with children in my constituency losing out."
