Many years back, predictions were made for several countries (mostly Asian countries) for the greatest population. However, many of those predictions fitted accurately while some didn’t. Similarly, according to the data analysis and calculations, predictions are made for the countries likely to observe a drastic increase or decrease in their population by the 2100s.
As per the population analysis of 2020, out of ten, five countries with a larger population were Asian countries. However, the population graph of the world won’t be the same in 2100, and the picture would somewhat be like; five most populous countries will be from Africa. The Asian countries that are the leading 5 in today’s rank will continue to grow in population but at a comparatively slower rate. On the other hand, countries, including Bangladesh and China, are expected to have a decrease in population rate mainly because of their higher living standards and expensive education system.
