Question
India has a population of 1 billion and current population growth is 1.9 %, what is the doubling time?a.37 yearsb.15 yearsc.10 yearsd.100 years
Solution
The doubling time of a population can be estimated using the rule of 70, which is calculated by dividing the number 70 by the growth rate.
Here's the step-by-step calculation:
-
Identify the growth rate: The growth rate given is 1.9%.
-
Apply the rule of 70: Divide 70 by 1.9.
70 / 1.9 = approximately 36.84 years
So, the doubling time of India's population, given a constant growth rate of 1.9%, is approximately 37 years. Therefore, the answer is a. 37 years.
