Population Decline 2015-2050
In 2050 the world population is estimated to have reached 9.8 billion. India will then be the largest country by population (1.7 billion), followed by China (1.4 billion). The USA will no longer be the third-largest country in the world. This position will then be taken by Nigeria, with a population of 411 million.
The biggest absolute population decline between 2015 and 2050 will happen in China, followed by Japan and Russia. When it comes to relative population decline European countries are in the lead: Bulgaria first, followed by Latvia, Moldova, Ukraine, Croatia and Lithuania. The first non-European country on the top is the United States of America on 12th place.
In 2100 the world population is estimated to have reached 11.2 billion. By the end of the century, the African continent’s share of the global population will have risen to 49 per cent by the end of the century, increased from 16 per cent in 2018. At the same time, the global population is expected to have almost flatlined by then, meaning that the year 2100 could be the year of peak population after which the world’s population is expected to decline.
