Do you really think that the increase in population represents our victory against death? If so there is a good news for you. As per the announcement by the United Nations, by 2100, the world population will increase to 11.2 billion people. That’s not all! The UN also expects that the number will reach almost 9.7 billion by 2050. These estimates were presented today by the director of the United Nations Population Division; John R. Wilmoth in Seattle at the annual Joint Statistical meeting.
He also said that the constant increase in the population is due to the growth of population in Africa as its population by 2100 will increase up to 3.4 to 5.6 billion. It is pertinent to mention here that currently its population is 1.2 billion.
On the other hand, Asia may stand first in line, as usual and will remain the world’s most populous continent. The good news may be the number of individuals may decline to 4.9 billion by 2100. Moreover, the UN expect that by 2050, there will be around 5.3 billion people in Asia. Nevertheless, by 2100 the United States will grow to 450 million, as compared to its current population. Currently, there are 322 million people living in the US.
Having said that, numerous developing countries are struggling to control the growing population rate, especially China, where a couple can have only one child at a time. As we know the increasing rate of population may result in a shortage of facilities and the quality of life will be jeopardized.
As for the potential support ratio, which is the ratio of retired individual to the worker, it will also drop by 2100. The UN expects that the ratio in the US will fall to 1.9 from 4.0 workers for every retired individual. The ratios will be even less in Mexico, China and Germany.
It is also a matter of fact that although all these estimates are given in the form of a single number, the importance of the variables like fertility rates and life expectancy could not be denied.
