It is estimated that the world's second-largest continent will witness a spike in its population from 1.4 to 3.9 billion inhabitants by 2100.Eight nations with more than 10 million inhabitants, most of them in Europe, saw their populations shrink over the past decade. Japan is also seeing a decline due to its ageing population, losing more than three million inhabitants between 2011 and 2021.
