The report said India will overtake China as the world's most populated nation on earth in 2023.
"This is an occasion to celebrate our diversity, recognize our common humanity, and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates."
- Antonio Guterres, UN Secretary General
The population should reach 8.5 billion in 2030 and 9.7 billion by 2050, before reaching a peak of 10.4 billion in the 2080s and staying there until 2100.
