Assuming a world population of 6,800,000,000 in 2009 and an annual growth rate of 1.1 percent, how many people will be added to the world’s population within the next year?
Explanation
Answer - C - Assuming a world population of 6,800,000,000 in 2009 and an annual growth rate of 1.1 percent, 7,480,000,000 people will be added to the world’s population within the next year.
Key Takeaway: The last one hundred years have seen a rapid increase in population due to medical advances and massive increase in agricultural productivity made possible by the Green Revolution. In 2009, the estimated annual growth rate was 1.10%. In that year, the human population increased by about 74 million.
It is interesting to note that since 2006, although the population has greatly increased, the annual growth of the population has actually declined.
