The global population could fall to six billion by the end of the century if there is “unprecedented investment” in tackling poverty and inequality, researchers have said.
In a report assessing how different policies would have an impact across the world, the population could peak at 8.5 billion in 2040 before declining by 2100 – but only if “extreme poverty is eliminated” alongside the adoption of “successful policies for economic development.”
On current economic trends, the experts said the population could peak at 8.6 billion in 2050 before dropping back to 7 billion in 2100.
Experts said economic development is associated to a fall in fertility rates because it improves access to education and health services.
The study was commissioned by the Club Of Rome, a non-profit organisation which addresses “the multiple crises facing humanity and the planet” – but its figures are in contrast to UN forecasts which show the population reaching 9.7 billion in 2050 and peaking at 10.4 billion in the 2080s.
