This report by the Child of the North group highlights how children born into the poorest fifth of families in the UK are almost 13 times more likely to experience poor health and educational outcomes by the age of 17.
The report also highlights how northern schools are losing out on hundreds of pounds of funding per pupil compared to those in London.
Over the last 10 years, ongoing inequalities in funding have meant schools in the North of England have received less money from the National Funding Formula (NFF) on average than their southern counterparts.
The new analysis found that on average pupils in London received 9.7% more funding than those in the North.
Schools in London received an average of £6,610 per pupil compared to £6,225, £5,956, and £5,938 in the North East, North West, and Yorkshire and the Humber, respectively.
