Population Growth Rate formula

Definition

The population growth rate formula is used to calculate how fast a population is growing or declining over a specific period of time. It takes into account both natural increase (births minus deaths) and net migration (immigration minus emigration).

Analogy

Imagine a roller coaster ride that represents population growth. The population growth rate formula helps us determine if we're on an uphill climb (positive growth rate), going downhill (negative growth rate), or staying level (zero growth rate).
