The "eye-opening" Office of National Statistics over-90s data has reinforced the need for regulated financial advice in long-term care, Just Retirement has said.
The ONS's publication of the Very Old (including Centenarians) 2002-2011, England and Wales, shows that in 2011 there were 440,290 people aged 90 and over - just under 1% of the total population.
Just Retirement said the 26% increase in the number of 90-year-olds in less than 10 years was eye-opening.
The figures also showed in 2011 the number of centenarians was estimated to be 11,700.
And there were estimated to be 2.7 women per man aged 90 and over and 6 women per man aged 100 and over.
Steve Lowe, director at Just Retirement, said: "It is common knowledge that people are living longer. Planning for the provision of long term care will be a vital part of planning for retirement and old age.
"We fully support the Government's plans for regulated financial advice in the draft Care and Support Bill, and the creation of a national awareness programme. It is important people working now, as well as those approaching and in retirement, understand the true costs of long term care."
