Mayor of London Sadiq Khan show what he says is a clear link between poverty in the capital and the rise in serious youth violence.
The data shows that the poorest areas of London are most likely to experience the highest levels of serious crime among youngsters.
Richmond upon Thames has the lowest level of youth violence in the capital - and it is also the least deprived borough in the city, based on official figures.
Tower Hamlets in east London is one of the poorest areas in England - and the data shows it has now one of the highest rates of youth violence in the capital.
Other official statistics, such as rates of adolescent mental health, teenage pregnancies and domestic abuse, also reveal a correlation between serious youth violence and the poorest areas of London.
Khan said: "There are still some who say that to acknowledge this link between poverty, deprivation and crime is somehow to excuse criminality and to let the criminals off the hook. I say this is dangerous rubbish. There's never any excuse for criminality. But we have to face the reality that for some young people growing up today, violence has become normalised. And - with hope at rock bottom... turning to crime and gangs has become an all too easy route to satisfy the lure of gaining respect and money - however misguided this is."
