The population of the world in 2050.
Answer to Problem 1MC
Option (d) 9.2 billion.
Explanation of Solution
World population data from 1600 to 2100 according to United Nations figure is shown in the Figure 4-1. The graph indicates that there is a huge increase in population from around mid1950, however the rate of increase is slowing down from its peak of 2 percent/year to about half the population of that today.
There are various factors for the decrease in the trend some of them include Infertility rate, turmoil, war, more amount of aged population and less young population is countries like china. In spite of the slowing trend the world population is expected to increase to between 9.2 billion and 11.8 billion in 2050.
Conclusion:
World population from 1600 to 2100 according to United Nations figure is shown in the Figure 4-1 indicates that the number of people in the world is expected to reach 9.2 billion in 2050 years. Therefore, the correct option is (d) 9.2 billion.
The population expected to reach 9.2 billion in 2050. Therefore, option (a) is incorrect.
The population expected to reach 9.2 billion in 2050. Therefore, option (b) is incorrect.
The population expected to reach 9.2 billion in 2050. Therefore, option (c) is incorrect.
