A 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 around 40,175 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 22 GRG-validated living supercentenarians (as of 4 August 2022), all of whom are female. The current oldest validated living woman (and person) is Kane Tanaka, 118, and the oldest validated living man is currently under review.
