World population is projected to hit 8 billion

The population of the world is expected to surpass 8 billion on November 15, 2022.

It is anticipated that the world’s population will exceed 8 billion on November 15, 2022, and that India would overtake China to become the most populated nation in the world in the year 2023.

The eighth billionth person on Earth is expected to be born this year, making this year’s World Population Day a historic occasion. This is a time to celebrate our differences, acknowledge our shared humanity, and marvel at medical advances that have lengthened life expectancies and significantly lowered maternal and infant death rates, according to UN Secretary-General António Guterres. At the same time, he continued, “it is a moment to reflect on where we still fall short of our obligations to one another and a reminder of our shared responsibility to care for our planet.”

In 2020, the world’s population actually decreased by less than 1%, growing at its sluggishest rate since 1950. According to the United Nations’ most recent estimates, the world’s population may reach 8.5 billion people in 2030 and 9.7 billion by 2050. The population is predicted to peak at 10.4 billion people in the 2080s and stay there until 2100.

According to World Population Prospects 2022, fertility has decreased significantly in many nations during the past few decades. Currently, two-thirds of the world’s population reside in regions or nations with lifetime fertility rates below 2.1 births per woman, or roughly the number needed for a population with low mortality to experience long-term growth of zero. Between 2022 and 2050, it is predicted that the populations of 61 countries or regions would decline by 1% or more. This is due to persistently low fertility rates and, in some cases, high emigration rates.

Eight nations—the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and the United Republic of Tanzania—will account for more than half of the expected growth in the world’s population by 2050. More than half of the increase forecast through 2050 is anticipated to come from sub-Saharan African nations.

According to Liu Zhenmin, the Under-Secretary-General of the United Nations for Economic and Social Affairs, “the relationship between population growth and sustainable development is complicated and multilayered.” “Eliminating poverty, fighting hunger and malnutrition, and expanding the coverage of health and education systems are all made more difficult by the rapid rise of the world’s population.”

On the other hand, meeting the Sustainable Development Goals will help to slow down population growth globally and reduce fertility rates, particularly those relating to health, education, and gender equality.
