population size
Number of individuals
Population size is the total number of individuals in a defined group—a species in an ecosystem, residents of a city, or subjects in a study.
The term appears frequently in ecology, demographics, and statistics, where it determines sampling methods and analytical power.
The population size of the island's deer herd has doubled in a decade.
