The report noted that in most countries of sub-Saharan Africa, as well as in parts of Asia and Latin America and the Caribbean, the share of population at working age (between 25 and 64 years) had been increasing thanks to recent reductions in fertility.Ĭountries needed to invest in the further development of their human capital by ensuring access to health care and quality education at all ages and by promoting opportunities for productive employment and decent work, the report recommended. Yet in 2021, life expectancy for the least developed countries lagged seven years behind the global average. Further reductions in mortality are projected to result in an average global longevity of around 77.2 years in 2050. Global life expectancy at birth reached 72.8 years in 2019, an improvement of almost nine years since 1990. This includes establishing universal health care and long-term care systems and improving the sustainability of social security and pension systems. At that point, it is expected that the number of persons aged 65 years or over worldwide will be more than twice the number of children under age five and about the same as the number under age 12.Ĭountries with ageing populations should take steps to adapt public programmes to the growing numbers of older persons, the report recommended. The share of global population at ages 65 and above is projected to rise to 16 per cent in 2050, from 10 per cent in 2022. More than half of the projected increase in the global population up to 2050 will be concentrated in eight countries:Ĭountries of sub-Saharan Africa are expected to contribute more than half of the increase anticipated through 2050. The populations of 61 countries or areas are projected to decrease by one per cent or more between 20, owing to sustained low levels of fertility and, in some cases, elevated rates of emigration. Today, two-thirds of the global population lives in a country or area where lifetime fertility is below 2.1 births per woman, roughly the level required for zero growth in the long run for a population with low mortality.
World Population Prospects 2022 also states that fertility has fallen markedly in recent decades for many countries. It is projected to reach a peak of around 10.4 billion people during the 2080s and to remain at that level until 2100.
The latest projections by the United Nations suggest that the world’s population could grow to around 8.5 billion in 2030 and 9.7 billion in 2050. It is growing at its slowest rate since 1950, having fallen under one per cent in 2020. The global population is projected to reach eight billion November 15, 2022, according to the report. The world's two most populous regions in 2022 were Eastern and South-Eastern Asia, with 2.3 billion people, representing 29 per cent of the global population, and Central and Southern Asia, with 2.1 billion, representing 26 per cent of the total world population.Ĭhina and India accounted for the largest populations in these regions, with more than 1.4 billion each in 2022.India is projected to surpass China as the world’s most populous country in 2023, according to World Population Prospects 2022, released on World Population Day, July 11, 2022. The report said that "India is projected to surpass China as the world's most populous country during 2023. This is an occasion to celebrate our diversity, recognise our common humanity, and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates, UN Secretary-General Ant nio Guterres said.Īt the same time, it is a reminder of our shared responsibility to care for our planet and a moment to reflect on where we still fall short of our commitments to one another, he added.
This year's World Population Day (July 11) falls during a milestone year, when we anticipate the birth of the Earth's eight billionth inhabitant.
