Getty Images India is set to be the world’s most populous country next year, overtaking China with its 1 . 4bn people, according to UN figures.
By this November, our planet will be home in order to 8bn.
Yet population growth is not really as rapid since it used to be.
It is now at its slowest rate since 1950 and is set to maximum, says the UN, around the 2080s around 10. 4bn though some demographers believe that could happen even sooner.
But the population from the world is growing unevenly.
More than half the particular growth we will see in the next 30 years will happen in only eight countries : the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.
At the same time, some of the world’s most developed economies are already seeing population decrease as fertility rates fall below 2 . 1 children per woman, which is known as the “replacement rate”. Within 61 countries, the particular report says, populations will decline simply by at least 1% by 2050.
With one of the lowest fertility prices in the world (at one 15 children per woman), China offers announced that its population is due to start decreasing next year – a lot earlier than previously thought. That is despite the nation abandoning its one child policy in 2016 and introducing incentives for young couples to have two or more kids.
As India’s populace continues to grow it will almost certainly overtake China as the country with the greatest population in the world.
Fertility rates are usually falling globally — even in many of the nations where the population will be expanding. That is mainly because, as previous generations expand, there are more people having children, even if individually those individuals are having fewer kids than their mother and father did.
Growth is also largely thanks to advancements in medicine and science which imply that more children are surviving into adulthood and more adults into old age. That will pattern is likely to continue, which means that by 2050 the global average life expectancy will be around seventy seven. 2 years.
But this pattern means that the particular share of the global population aged 65 years or above is projected to increase from 10% this year to 16% within 2050. Again the distribution will be bumpy with some countries, within East Asia plus Western Europe, already seeing more extreme conditions in ageing.
