FIGURES showed that on Census day, which took place on March 27 last year, the number of women over 90 was 315,000, nearly three times higher than the number of men over that age, at 114,000.
The total population figure was about half a million larger than estimates had shown a year earlier.
The population of England was 53 million while Wales was 3.06 million.
The population of Northern Ireland also increased to 1,801,900, an increase from around 1.7 million in 2001.
Figures for Scotland will be released later this year.
