Description: Presented at Living to 100 Symposium, January 2002. This paper is a first attempt to assess which group of mortality trajectories proposed by various researchers is confirmed by empirical data between the age of 110 and 115 years when the exponential trajectories on the one hand and the logistic or quadratic trajectories on the other hand have diverged sufficiently.
