A concerted, international research effort is presently undertaken with the goal of establishing a database that will allow the best possible description of the mortality trajectory beyond the age of 110. Specifically, the objective of this concerted effort is to gather complete lists of validated supercentenarians (i.e., persons aged 110 and above) in as many countries as possible. These lists should be free of ascertainment bias. They will be assembled in the International Database on Longevity (IDL). The IDL will be a research database available on the internet to qualified scholars. The database will contain complete and validated lists of supercentenarians, arranged by nationality at birth. These lists will include supercentenarians who are alive as well as person who have died. For each supercentenarian, the database will include an anonymous case number, information on his/her date of birth, date of death (if known), sex, on the methods used to validate the person's age, and how the person was ascertained. |
