![]() Generating high-quality life tables for long-lived species living in the wild is challenging for various reasons, with the long-term commitment to individual-based monitoring foremost among them. Specifically, age-specific survivorship l x and fertility m x, (where x indicates a discrete age class) are all that are needed to estimate the relative contribution of an age x individual to the future size of the population (the ‘reproductive value’, v x), the life expectancy of an age x individual ( e x), the average lifetime reproductive success (the average lifetime number of daughters per mother, R 0), the asymptotic population growth rate ( λ), the stable fraction of individuals of age x in a steadily growing or declining population (the age x entry in the ‘stable age distribution’, w x), and the average number of years between a female’s birth and the birth of her offspring (the ‘generation time’, G). The life table has a long history as a means of summarizing census and birth data to describe how survival and fertility vary with age, and of using these underlying parameters to estimate useful population-level statistics 1. These data have high potential for reuse they derive from continuous population monitoring of long-lived organisms and will be invaluable for addressing questions about comparative demography, primate conservation and human evolution. We used bootstrapping to place confidence intervals on life-table summary metrics ( R 0, the net reproductive rate λ, the population growth rate and G, the generation time). We also calculated reproductive value, life expectancy, and mortality hazards for females. In all species, our survival estimates for the dispersing sex are affected by heavy censoring. Using one-year age-class intervals, we computed point estimates of age-specific survival for both sexes. We provide male and female census count data, age-specific survivorship, and female age-specific fertility estimates for populations of seven wild primates that have been continuously monitored for at least 29 years: sifaka ( Propithecus verreauxi) in Madagascar muriqui ( Brachyteles hypoxanthus) in Brazil capuchin ( Cebus capucinus) in Costa Rica baboon ( Papio cynocephalus) and blue monkey ( Cercopithecus mitis) in Kenya chimpanzee ( Pan troglodytes) in Tanzania and gorilla ( Gorilla beringei) in Rwanda.
