World Population Prospects 2022, UN report published on 11 July 2022, projects world population to reach 8 billion on 15 November 2022. India is projected to surpass China as the world’s most populous country during 2023.

According to the latest projections by the United Nations suggest that the global population could grow to around 8.5 billion in 2030, 9.7 billion in 2050 and 10.4 billion in 2100. The global human population will reach 8.0 billion in mid-November 2022 from an estimated 2.5 billion people in 1950, adding 1 billion people since 2010 and 2 billion since 1998. Globally, the world counts slightly more men (50.3 per cent) than women (49.7 per cent) in 2022. By 2050, it is expected that the number of women will equal the number of men.

Population growth is caused in part by declining levels of mortality, as reflected in increased levels of life expectancy at birth. Globally, life expectancy reached 72.8 years in 2019, an increase of almost 9 years since 1990. Further reductions in mortality are projected to result in an average longevity of around 77.2 years globally in 2050.

Life expectancy at birth for women exceeded that for men by 5.4 years globally, with female and male life expectancies standing at 73.8 and 68.4, respectively. A female survival advantage is observed in all regions and countries, ranging from 7 years in Latin America and the Caribbean to 2.9 years in Australia and New Zealand.
