The figure meant 1 billion people had been added to the global population in just 12 years. Middle-income countries, mostly in Asia, accounted for most of the growth over the past decade, gaining some 700 million people since 2011. India added about 180 million people, and is set to surpass China as the world’s most populous nation next year.
But even while the global population reaches new highs, demographers note the growth rate has fallen steadily to less than 1% per year. This should keep the world from reaching 9 billion people until 2037. The UN projects the global population will peak at around 10.4 billion people in the 2080s and remain at that level until 2100.
Most of the 2.4 billion people to be added before the global population peaks will be born in sub-Saharan Africa, according to the UN, marking a shift away from China and India.
Having more people on Earth puts more pressure on nature, as people compete with wildlife for water, food and space. Meanwhile, rapid population growth combined with climate change is also likely to cause mass migration and conflict in coming decades.
And whether it’s food or water, batteries or gasoline, there will be less to go around as the global population grows. But how much they consume is equally important, suggesting policymakers can make a big difference by mandating a shift in consumption patterns.
Resource pressure will be especially daunting in African nations, where populations are expected to boom, experts say. These are also among the countries most vulnerable to climate impacts, and most in need of climate finance.
