To be sure, the headline deceleration effect seen in global population numbers hides the geographical and income-wise differences in demographic dynamics.

This is the longest time it has taken to add another billion people since 1950, the earliest period for which WPP numbers are available. It is likely to cross the 8-billion mark on Novemand is expected to cross the 9-billion figure in 2038. The latest WPP projections also show that global population has already entered a phase of significant deceleration. Conversely, achieving the Sustainable Development Goals, especially those related to health, education and gender equality, will contribute to reducing fertility levels and slowing global population growth.” “Rapid population growth makes eradicating poverty, combatting hunger and malnutrition, and increasing the coverage of health and education systems more difficult. “The relationship between population growth and sustainable development is complex and multidimensional” said Liu Zhenmin, UN under-secretary-general for Economic and Social Affairs, according to a statement by the UN’s department of economic and social affairs. China’s population, which is expected to have peaked at 1.425 in 2021, will decline significantly to reach just 0.77 billion by 2100.Īccording to the report, India’s population stands at 1.412 billion in 2022. This will catapult India to the top of the population ranking, with a peak figure likely being hit in 2064 when the country is predicted to have 1.697 billion people.īy 2100, the number will gradually come down to 1.53 billion.

The UN numbers also predict that the global population is expected to cross the 8 billion mark this year, even though it has already entered a phase of significant deceleration.Īccording to the World Population Prospects 2022 (WPP), released by the United Nations Department of Economic and Social Affairs (UNDESA) on Monday, India’s population will reach 1.428 billion on July 1, 2023, which will be marginally higher than the 1.426 billion figure for China at the time. Sustained high fertility and rapid population growth present challenges to achieving sustainable development, it said.India will replace China as the most populous country in the world in 2023, and it will continue to have that distinction till 2100, according to the latest population projections by the United Nations.

Women and men are expected to be equal in numbers by 2050 as the current global count of 49.7% women compared to 50.3% men is expected to be inverted, the report said. In India, the total fertility rate may decline to 1.29 births per woman by 2100 instead of the UN’s earlier estimate of 1.69 births, according the report, which cites data from the Institute for Health Metrics and Evaluation. The global population is expected to grow to 9.7 billion in 2050 and 10.4 billion in 2100, lower than the UN’s 2019 estimate of 11 billion. Population growth rates in Europe and Northern America were almost zero in 20, data show. Numbers in sub-Saharan Africa may almost double by late 2040s to cross 2 billion. Lower mortality rates and demographic changes may ensure that central and southern Asia become the world’s most-populous region by 2037. An earlier report projected India surpassing China by 2027. A Chinese official had earlier this year estimated that the country’s population may peak as early as 2022 as its population of 1.41 billion grew at the slowest pace since the 1950s, according to government data. China is expected to experience an absolute decline in its population as early as next year, the report said.
