What will be the global population in 100 years? Arumainayagam

1.    What will be the global population in 100 years? For the past few hundred years, the global population has increased at an alarming rate. The latest predictions show that the population will eventually plateau somewhere between 10 and 12 billion people, assuming the current trends continue. Understanding how the global population will change is essential to determine how to make the planet more sustainable. 

2.    In order to make projections for the world population, scientists must consider birth and death rates to assess the net population growth. Because different parts of the world are growing at different rates, scientists would need to look at the birth and death rates of each country. Every five years, the UN collects data from each country to update their current growth projection. Analysts must also consider factors such as economic growth, life expectancy, and changes in access to health care, as all of these can affect the population growth of a country. It’s not enough to make projections based on the current trends since the trends themselves will change along with the population, which is why there is a range in what the population could be in the future.

The accuracy of population projections can depend on how accurately a country can measure its total population. Some countries do not conduct a national census frequently, and others do not have an accurate system to estimate their entire population. Population analysts can only use the information they have about the past to make projections for the global population. It would be difficult to account for changes in growth rates because they can be influenced by changes in political and economic environments, which are very difficult to predict. As a result, there is uncertainty with what the population will be in 100 years. Population analysts can be reasonably sure that the population growth rate will slow down because the birth rate in almost all countries has been declining for decades.
