Mortality statistics from three captive populations of chimpanzees (Pa
n troglodytes) were combined to generate standard model life tables fo
r each sex in this species. The model is compared to an estimate of su
rvivorship of a group of wild animals, and is applied to an incomplete
data set to illustrate how the model may be used to extend estimates
of mortality statistics to missing older ages. (C) 1995 Wiley-Liss, In
