England and Wales are ageing at their fastest rate since records began, according to official figures.
Results of Census 2011, released by the Office for National Statistics, showed there were 430,000 people in England and Wales aged 90 and over, compared with only 13,000 when the Census was carried out in 1911.
The median age of the population has increased to 39 in 2011, up from 35 in 2001 and 25 in 1911.
The figures also revealed the population has grown by 3.7 million in the last decade to 56.1 million in the largest rise since records began.
But there was also an increase in the number of under fives, with more than 400,000 more in 2011 compared with 2001.
The ONS results show that every region in England and Wales had a larger population in 2011 than 10 years earlier.
The largest increase in population was in London, which grew by 12 per cent, gaining more than 850,000 inhabitants and taking its total population to more than eight million.
