supercentenarian is a person who lived until or past their 110th birthday. About 1 in 1000 of centenarians are 110+, so it's a rare achievement in longevity. A supercentenarian, on their 110th birthday, would have lived 40,150 days and when a supercentenarian turns 114 years, 28 days old then he/she would have lived about one million hours of life. A study says the USA, Japan, France, UK and Italy are the top 5 countries with the most supercentenarians. There are estimated to be 300-450 living supercentenarians in the world. There are 45 verified living supercentenarians (as of 31 Dec 2016), out of which 44 are female and one are male. The current oldest verified living woman is Nabi Tajima, 117, and the oldest verified living man is currently under review.
