Answer :
When the growth rate of the population rises, then the doubling time tends to get fall.
The given statement is true.
What is doubling time?
Doubling time is the time taken by a quantity to get twice in size or value at a fixed rate of growth.
The doubling time of population can be determined by dividing 70 by the rate of growth and this method is also known as Rule 70.
For instance, the rate of growth is given as 10% so, the doubling time comes out to be 7 years (70/10) and if the rate rises to 12%, then the doubling time falls to be almost 5 years (70/12).
Therefore, it has been analyzed that the doubling time gets reduced when the rate of growth increases.
