The official projections, published on Monday, also said that females had more of a chance than reaching 100 years than males did.

The report – called What Are the Chances of Surviving to Age 100? – said that one in three babies born in 2012 would reach 100 in 2112,

It said 40 per cent of baby girls and just under a third of baby boys born this year would reach their 100th birthdays.

That means 156,000 of the girls and 135,000 of the boys that make up the 826,000 people born this year will live to be centenarians.

Over 95,000 people aged 65 in 2012 are expected to receive a card from the Monarch on their special day in 2047.

Figures say only 10 per cent of men aged 65 this year and 14 per cent of women the same age would get to 100.

While there were only 600 centenarians in 1961, there are estimated to be 14,500 this year.

David Sinclair, head of policy and research at the International Longevity Centre UK, said: “It is of course good news that so many more people are living longer, but there is a big ‘but’. In many ways today’s centenarians are unrepresentative.

“They are people who have escaped cancer, heart attack and stroke and so they are actually healthier than many people younger than them. Now that we are getting so much better at keeping people alive, that will no longer be the case.

“We will be older, but in worse health, and at high risk of living alone in unsuitable accommodation.

“The other problem is that we are very poor at forward planning, as politicians and individuals. We deal with the problems that are under our noses, but even problems two or three years away seem quite distant enough to put off.

“When you’re talking about forecasts for a time half a century away and more, I see no evidence that we are putting in place the measures to deal with it.”
