The correct answer is Option B: 3%.
In 2016, Sub-Saharan Africa, doubling time is 23.3 years, thus Growth rate is 3%.
<h3>What is doubling time?</h3>
- The doubling time is the time taken by a population to double in its size.
- This concept is applied to population growth, inflation, resource extraction, consumption of goods, the volume of malignant tumors, and many other things that tend to grow over time.
- There is an important relationship between the percent growth rate and its doubling time known as “the rule of 70”: to estimate the doubling time for a steadily growing quantity, simply divide the number 70 by the percentage growth rate.
- Therefore, Growth rate is 70 divided by doubling time (70/ doubling time).
- Here, Doubling time= 23.3 years.
- Growth rate= 70/23.3= 3%
