Question

How is the Growth Rate of Population Calculated?

Answer 1

The population growth rate is calculated using the following formula:

Growth Rate = (Birth Rate − Death Rate) ± Net Migration Rate

• Birth Rate = Number of births per 1,000 people per year
• Death Rate = Number of deaths per 1,000 people per year
• Net Migration Rate = Difference between people entering and leaving the region

Example:

If the birth rate is 25, the death rate is 10, and net migration is + 2 per 1,000 people, then:

Growth Rate = 25 − 10 + 2 = 17

Per 1,000 people ⇒ 1.7%
