World population reaches 8 billion but India seeing a marked slowdown - Check figures

The world on Tuesday (November 15, 2022) welcomed its 8th billion inhabitant, a remarkable milestone for humanity that is set to propel India to become the world's most populous country in 2023, surpassing China. As the population clock flashed 8,00,00,00,000 (800 crores), the United Nations (UN) described the global population reaching the mark as a "remarkable milestone" given that the human population numbered under one billion for millennia until around 1800, and that it took more than 100 years to grow from one to two billion. The world reached from seven billion to eight billion in 12 years.

"The growth of our population is a testament to humanity's achievements, including reductions in poverty and gender inequality, advancements in health care, and expanded access to education," the United Nations Population Fund (UNFPA) said.

India, however, is experiencing a marked slowdown

India, formerly a powerful driver of the number of people on the planet, however, is experiencing a marked slowdown.

India's annual population growth has averaged 1.2% since 2011, compared with 1.7% in the 10 years previously, government figures show.

Further slowing can be expected. India's total fertility rate (TFR) - children per woman - fell to 2 in the latest assessment period, for 2019-2021, from 3.4 in 1992-93, according to a government report issued last month. It is estimated that the average must be 2.1 for the population to reproduce itself.

Contraceptives, education contributed to decline in fertility rates

Increasing use of contraceptives and rising education among girls could have contributed to the decline in fertility rates, the government says.

The use of family-planning methods jumped to 66.7% in 2019-21 from 53.5% in 2015-16. That indicated that India's national population policies and health systems were working, the UNFPA told the news agency Reuters.
