THE UK census paints a picture of an ageing population, with 430,000 people in England and Wales aged 90 and over, compared with only 13,000 when the Census was carried out 100 years earlier in 1911.
The median age of the population has increased to 39 in 2011, up from 35 in 2001 and 25 in 1911.
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%, gaining more than 850,000 inhabitants and taking its total population to more than eight million.
