Population growth rate is the rate at which the number of individuals in a population increases in a given time period, expressed as a fraction of the initial population.

The population is one of the important factors which helps to balance the environment, the population should be in a balance with the means and resources.

**Formula to calculate population growth rate.**

**Example:**

Suppose a town’s new population is 5,000,000, if the original population was 4,500,000, calculate the population growth rate.

Therefore, the population growth rate is 11%.
