A population consists of all the organisms of a given species that live in a particular area. The statistical study of populations and how they change over time is called demography. Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume.

An age-sex pyramid is a "snapshot" of a population in time showing how its members are distributed among age and sex categories.
