To calculate the growth rate, you simply subtract the death rate from the birth rate. In this case, the growth rate (r) of the emperor penguin population in Antarctica is 0.3 – 0.1 = 0.2 new individuals per existing individual, per year.
How do you calculate the death rate?
- Definition: CRUDE DEATH RATE is the total number of deaths to residents in a specified geographic area (country, state, county, etc.) divided by the total population for the same geographic area (for a specified time period, usually a calendar year) and multiplied by 100,000.
- Technical Notes:
What is the difference between the birth rate and the death rate?
Births and deaths are natural causes of population change. The difference between the birth rate and the death rate of a country or place is called the natural increase. The natural increase is calculated by subtracting the death rate from the birth rate.
