Top 10 Country Population History & Projection (1850-2100)

This video shows the Top 10 countries with most population from 1850 to 2100 based on the Angus Maddison Project. It gives a brief history of the world since the 1800s. Asia (China and India) had the most population since the beginning of human civilization. But if the UN projections are accurate enough, Africa might become the most populous continent within the next century.
This is a list of countries and other inhabited areas of the world by total population, based on estimates published by the United Nations in the 2020 revision of World Population Prospects.[2][3] These figures refer to the de facto population in a country or area as shown in the "estimates" section.

Population refers to a collection of humans. Demography is a social science which entails the statistical study of human populations. Population in simpler terms is the number of people in a city or town, region, country or world; population is usually determined by a process called census.
