Concept explainers
(a)
Interpretation: The current rate of population growth, as percentage per year of France should be estimated.
Concept Introduction:
As per records, about 8000 B.C., the world population is approximately 5 million. It grew up to 200 million from 8000 year to 1 A.D, with growth rate 0.05% per year.
This change is due to industrial revolution. During the 20th century, the population of world increases from 1.65 to 6 billion. In 1970, the population was half of the current population.
The annual percentage growth rate is calculated by dividing percent growth by number of years.
(b)
Interpretation: The current rate of population growth, as percentage per year of Bolivia should be estimated.
Concept Introduction:
