These models can be used to describe the trajectory of population growth when resources are abundant, its maximum size when resources are limited, or how rapidly in space it expands into new territory.

Populations consist all of the species living within a specific area, and populations fluctuate based on a number of factors: seasonal and yearly changes in the environment, natural disasters such as forest fires and volcanic eruptions, and competition for resources between and within species. The statistical study of population dynamics, demography, uses a series of mathematical tools to investigate how populations respond to changes in their environments.

Various methods can be used to measure the size and density of a population. For example, scientists often use quadrats to do this for plants.  Dispersion patterns can give scientists information about a particular population. Three common dispersion patters are uniform, random, and clumped.
