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 13 September 2021), 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.
