According to a United Nations estimate released on Monday, India will overtake China as the world’s most populated nation in 2023, with both countries having more than 1.4 billion citizens this year. However, high fertility would pose a barrier to economic progress.
According to a research issued on World Population Day, the world’s population, which is expected to exceed 8 billion by November 15 this year, might expand to 8.5 billion in 2030 and 10.4 billion in 2100 as the rate of death lowers.
According to the domestic census, which is done once every ten years, India’s population was 1.21 billion in 2011. The government had postponed the census until 2021 because to the COVID-19 epidemic.
According to UN projections, the world’s population is rising at its slowest rate since 1950, and will dip below 1% in 2020.
In 2021, the global population’s average fertility was 2.3 births per woman during a lifetime, down from over 5 births in 1950. Global fertility is expected to fall even more by 2050, to 2.1 births per woman.
“This is an occasion to celebrate our diversity, recognize our common humanity, and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates,” said UN Secretary-General António Guterres in a statement.
Nonetheless, he remarked that a rising population reminded us of our shared duty to care for the world and to “reflect on where we still fall short of our commitments to one another,”
Referring to an earlier World Health Organization report that estimated approximately 14.9 million deaths from the COVID-19 pandemic between January 2020 and December 2021, the UN report stated that global life expectancy at birth fell to 71 years in 2021 from 72.8 years in 2019, owing primarily to the pandemic.
According to the United Nations, eight nations will account for more than half of the predicted rise in world population between now and 2050: Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and the United Republic of Tanzania.
Sub-Saharan African countries are estimated to provide more than half of the projected growth until 2050.
However, the population of 61 nations is expected to reduce by 1% or more between 2022 and 2050, owing to a decline in fertility.
