This is called projecting the population into the future and is a key step in population analysis for understanding the prospects of a population to increase, decrease, or even go extinct.

This results in a classic "J"-shaped graph of population size over time. For populations that can breed throughout the year this is called exponential growth. Most organisms, however, are restricted to breeding at certain times of the year, which results in geometric growth.

These and related quantities such as survival are called demographic rates.

These and related quantities such as survival are called demographic rates. Understanding the conceptual importance and mathematical characterization of these rates allows us to understand how and why a population changes over time.
