BOYS born in Yorkshire can expect to die, on average, five years earlier than those born in affluent areas in the South.
This figure was calculated by the Chartered Society of Physiotherapy as part of its nationwide research into links between wealth and lifespan.
The research says boys born in Kirklees will live to the age of 75, as against the national average of 76.3.
Those born in affluent areas of southern England, such as east Dorset and districts such as Chelsea and Kensington in London can expect to celebrate their 80th birthday.
The figures have led to the call for more emphasis on preventing ill-health, with the removal of inequality at the top of the agenda.
Phil Gray, the society's chief executive, said: "It is sadly still a fact of life that the poorer die younger.
"Lifespan in 2006 should not be determined by wealth."
Glasgow has the lowest life expectancy rate for boys born in the UK.
It currently stands at 69.3 years.
