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.
Back in 1950, four European countries were in the list of world’s most populous countries, and, now in 2020, only one European country is in the list, but, in 2100, there would be none. Children rate per woman right now is 2.5; however, due to the decrease in overall childbirth worldwide, UN researchers have predicted that the children rate per woman would drop to 1.9 by 2100, which would result in an incredible decrease in the population of the world.
