The “World Population Prospects 2022” report, which was released in honor of World Population Day, predicts that the world’s population will reach eight billion on Tuesday. In 2023, India is anticipated to overtake China as the world’s most populated nation.

According to the United Nations’ (UN) most recent estimates, the world’s population may reach 8.5 billion people in 2030 and 9.7 billion by 2050.

“This year’s World Population Day falls during a landmark year when we expect the birth of the Earth’s eighth billion inhabitants,” said UN Secretary-General Antonio Guterres. This is a time to celebrate our differences, acknowledge our shared humanity, and be in awe of health advances that have increased lifespans and significantly lowered mother and infant death rates.

He continued, “At the same time, it is a moment to reflect on where we still fall short of our commitments to one another and a reminder of our shared responsibility to care for our planet.”

Between 2022 and 2050, the populations of 61 nations are expected to decline by 1% or more as a result of low fertility rates and, in some circumstances, high emigration rates.

By 2050, eight nations—the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and the United Republic of Tanzania—are expected to account for more than half of the projected increase in the world’s population.

Globally, the life expectancy at birth increased to 72.8 years in 2019, an almost nine-year rise since 1990. It is anticipated that further mortality declines will lead to an average worldwide lifetime of roughly 77.2 years in 2050. But in 2021, the least developed nations’ life expectancy lagged 7 years behind the average worldwide.
