The life expectancy divide between Britain's more prosperous and deprived areas has widened to as much as 13 years, official figures revealed.
Though people across the country are in general living longer, statistics show children born in the South of England have a longer life ahead of them than those brought up in Scotland and the North.
A boy from London's affluent Kensington and Chelsea can now expect to survive 13.5 years longer than his counterpart in Glasgow City.
The figures, released by the Office for National Statistics (ONS), give a snapshot of life spans in every local area across Britain. They show the average life expectancy at birth now stands at 78.2 years for men and 82.3 years for women.
Statistically, the English have a longer future ahead of them than those living in the rest of the UK - peaking at 78.6 for men and 82.6 for women. The Scottish have the lowest life expectancy, reaching the average age of 75.8 years for men and 80.4 years for women.
A breakdown of different local areas revealed that boys in Kensington and Chelsea have a life span at birth of 85.1 years, while for girls this figure stands at 89.8 years. At the other end of the scale, in Glasgow City the lifespans were 71.6 years and 78 years respectively.
The gap between the two - 13.5 years - is greater than that of the previous period when it stood at 12.5 years.
The ONS report, which examined the population between 2004/06 and 2008/10, showed the divide also widened for girls - by 1.7 years.
Where previously a daughter born to parents in Kensington and Chelsea could expect to live 10.1 years longer than her Glaswegian counterpart, that figure now stands at 11.8 years. She is now expected to reach 89.8 years, while a girl living in Glasgow City is only expected to reach 78 .
Michelle Mitchell, director at Age UK, said: "What is concerning and seems ever more widening is the gap between life expectancy for people in different areas across the UK. This disparity reflects the inequalities that exist, particularly in relation to people's health, in certain areas of the country."
