Largest population of centenarians

The Twenty-third United States Census, known as Census 2010, counted 53,364 people aged 100 and older in the United States as of National Census Day, 1 April 2010. This represented 1.73 centenar¬ians per 10,000 people against a total population of 308,745,538. Supercentenarians — those aged 110 and older — represented 0.6 per cent of the centenarian population. In absolute terms, Japan ranks second, with official Japanese figures for 2010 of 44,449 centenarians. Measured against the total population, however, the US proportion of centenarians is about half the level found in Japan, which is 3.43 per 10,000 (Statistics Bureau of Japan, 2011).
