A 10-year life gap separates residents in Birmingham's prosperous suburbs from their counterparts in the inner city, a new study reveals.
The difference in life expectancy, highlighted in a report by pensions experts, was based on figures from the Office of National Statistics.
It was accompanied by a warning that people in the city's prosperous areas will have to save more for their pensions as they live longer, and calls for more targeted social investment in the poorer parts to help improve health and education.
According to the study by pension consultants Punter Southall, men in the Sutton Four Oaks ward can expect to live 2.4 years longer than the national average of 76 years. The figure for women is 1.2 years above the national 80.5 years.
This is in stark contrast to Ladywood, where the mortality rate for men is 7.4 years below the national average and for women 3.4 years below.
The most recent ONS figures for the city on a whole, from 2004 to 2006, show residents of Birmingham have a lower life expectancy than average by 1.8 years for men (77 years national average) and 0.8 years (81.3) for women.
The issues are due to be highlighted at a Punter Southall workplace pensions seminar in Birmingham on February 29 at the I0D Hub, in One Victoria Square.
Emma Skedgel, senior consultant at Punter Southall, said: "Where the life expectancy is higher than the national average, then perhaps it all relates to the contribution levels in terms of what people should be putting in. The link between increasing life expectancy and pensions is that, ultimately, people will need to contribute to a larger pension pot to provide for them at retirement."
The survey prompted calls from a city councillor for the Government to review its public health priorities.
Councillor Carl Rice (Lab Ladywood) said: "It is shocking. There are lots of reasons why this is the case in Ladywood including poor housing, low education levels, high unemployment. We know there is a lot we could do and should be doing.
"I have got one criticism of this Government in terms of public health. The massive extra investment of the health services tends to go into acute sector.
"There would be a far greater impact on life expectancy if we look at improved homes and education and look at healthy diet and public health areas, rather than just give.
"Not at the expense of the acute sector, but we have got to invest in local services to feel a real improvement."
In addition, Coun Rice said, Ladywood had the highest level of childhood obesity in Birmingham, which he felt would have a further impact on future statistics.
This, he said, was not "likely to get immediately better" unless various social issues were tackled.
"There is a lot we are trying to do," he said. "We want to increase the education attainment levels. There is a link between career, health and jobs.
"If there are more children with better education, they will be more likely to get better jobs and a better life.
"One additional problem we face is the turnover of population.
"Ladywood is not the preferred destination, but the destination that people come to when they move to Birmingham. But when they are new to the UK - not just Birmingham - language problems don't make it easier for teachers as the children have to learn English first.
"A lot of the housing is of a poor standard. We need to see real investment in housing, teachers having smaller classes and a far greater emphasis on public health."
Last night, a Department of Health spokesman said: "The Government is determined to reduce health inequalities and for the first time ever this is one of the department's top six priorities for the NHS.
"We welcome improvements in life expectancy. However there is more to do, which is why we have policies in place to address this."
