World population to hit 8b this year, UN report says

UNITED NATIONS－The global population is projected to reach 8 billion on Nov 15, with India projected to surpass China as the most populous country in 2023, said the United Nations on Monday, which was also World Population Day.

"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," UN Secretary-General Antonio Guterres said.

The growth rate is at its slowest since 1950, having fallen under 1 percent in 2020, according to the World Population Prospects 2022.

The world's population could grow to around 8.5 billion in 2030 and 9.7 billion in 2050 and peak at around 10.4 billion during the 2080s before steadying at that level until 2100, the UN report said. Countries in sub-Saharan Africa are expected to contribute more than half of the increase through 2050.

More than half of the projected increase up to 2050 will be concentrated in eight countries: the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and the United Republic of Tanzania.

"Rapid population growth makes eradicating poverty, combating hunger and malnutrition, and increasing the coverage of health and education systems more difficult. 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," said Liu Zhenmin, UN under-secretary-general for Economic and Social Affairs.

Fertility has fallen markedly in recent decades for many countries, the report said, noting that two-thirds of the global population today lives in a country or area where lifetime fertility is below 2.1 births per woman.

Due to sustained low levels of fertility and, in some cases, elevated rates of emigration, the populations of 61 countries or areas are projected to decrease by 1 percent or more between 2022 and 2050.

Average global longevity is projected to be around 77.2 years in 2050 with further reductions in mortality, as 2019 saw a global life expectancy at birth of 72.8 years, an improvement of almost 9 years since 1990.

Since 1990, World Population Day has been observed on July 11 to raise awareness of issues related to population growth around the world.
