Abstract A model of stochastic birth and death processes which includes demographic and environmental stochasticity is used to determine the chance of survival of small populations with overlapping generations. Mean life times dependent on the present size of the population and the probability of recovery are calculated. It is shown how the mean life time is related to the concept of minimum viable population. For moderate environmental noise, a critical individual number is found above which a population is relatively safe against extinction. The overwhelming importance of the environmental noise is demonstrated. It is shown that the mean life times increases with increasing capacity K in a way which is determined by the environmental noise. The smaller this noise the stronger is this increase.
