Enter the current population, number of years, and growth rate into the population growth calculator. The calculator will display the new population after the number of years entered. If you already know the final population and want to calculate the percent growth, visit the percent growth calculator linked below.

## Population Growth Formula

The following formula is used to calculate a population size after a certain number of years.

*x*(*t*) = *x*_{0} × (1 + *r*)^{ t}

- Where
*x*(*t*) is the final population after time t *x*_{0}is the initial population- r is the rate of growth
- and t is the total time (number of years

How to calculate population growth

**First, measure the initial population**Typically, when working on large scales like populations, only an estimate can be determined through calculations for the population size. Getting exact numbers is nearly impossible on this scale.

**Next, determine the growth rate**This is the % increase each year in population. Typically you would measure one year to the next to determine the growth rate.

**Determine the total time**Choose a total amount of years you wish to calculate the new population for.

**Calculate the new population**Enter the information from steps 1-4 into the popluation growth formula.

## FAQ

**What is population growth?**

Population growth is the increasing growth of a population due to reproducing.

**What is a population growth rate?**

A population growth rate is a rate at which a population increase every year, or per time period that is being analyzed.

**What type of growth do populations see?**

Typically population growth is exponential, however, at some point all populations hit a tipping point where they cant support their growth rate any longer due to many factors including health and food supply.
