Symbol Technologies's population is 5,400.

A prey
population growth
The population size of a predator species is directly controlled the availability (population size, etc.) of its prey species.
Population density
From a sample of a population, the properties of the population can be inferred.
The sumation (each stratum of population) of risk * population size. For example: (risk*population size of group 1) + (risk*population size of group 2) + ... + (risk*population size of group n)
