A supercentenarian (sometimes hyphenated as super-centenarian) is a person who has reached the age of 110 years. This age is achieved by about one in 1,000 centenarians. Supercentenarians typically live a life free of major age-related diseases until shortly before the maximum human lifespan is reached. Etymology The term "Supercentenarian", originally hyphenated as Super-centenarian, has existed since 1870. The terminology "Ultracentenarian", has also been used to describe someone over 100 years. Norris McWhirter, editor of Guinness World Records, used the term in association with age claim's researcher A. Ross Eckler Jr. in 1976, and the term was further popularised in 1991 by William Strauss and Neil Howe in their book Generations. The term "semisupercentenarian", has been used to describe someone from 105-109. Originally the term "supercentenarian" was used to mean someone well over the age of 100, but 110 years and over became the cutoff point of accepted criteria for demographers. Incidence The Gerontology Research Group maintains a top 30–40 list of oldest verified living people. The researchers estimate, based on a 0.15% to 0.25% survival rate of centenarians until the age of 110, that there should be between 300 and 450 living supercentenarians in the world. A study conducted in 2010 by the Max Planck Institute for Demographic Research found 663 validated supercentenarians, living and dead, and showed that the countries with the highest total number (not frequency) of supercentenarians (in decreasing order) were the United States, Japan, England plus Wales, France, and Italy. The first verified supercentenarian in human history was Dutchman Geert Adriaans Boomgaard (1788–1899), and it was not until the 1980s that the oldest verified age surpassed 115. History While claims of extreme age have persisted from the earliest times in history, the earliest supercentenarian accepted by Guinness World Records is Dutchman Thomas Peters (reportedly 1745–1857).. Other scholars, such as French demographer Jean-Marie Robine, consider Geert Adriaans Boomgaard, also of the Netherlands, who turned 110 in 1898, to be the first verifiable case, as the alleged evidence for Peters has apparently been lost. The evidence for the 112 years of Englishman William Hiseland (reportedly 1620–1732) does not meet the standards required by Guinness World Records.. Church of Norway records, the accuracy of which is subject to dispute, also show what appear to be several supercentenarians who lived in the south-central part of present-day Norway during the 16th and 17th centuries, including Johannes Torpe (1549–1664), and Knud
