According to a UN report, the world’s population will reach eight billion by November 15 of this year.
According to the study conducted for World Population Day, the world’s population will exceed eight billion in just over four months, 8.5 billion by 2030, and 10.4 billion by 2100 as a result of the mortality rate lowering.
According to UN predictions, population growth has slowed to its lowest level since 1950 and will be around 1% in 2020.
With each country having more than 1.4 billion citizens this year, India will overtake China as the world’s most populated nation in2023. However, the UN has cautioned that high fertility may hinder economic progress.
India’s population was 1.21 billion in 2011, according to the domestic census, which is conducted once a decade. The government had postponed the 2021 census due to the Covid-19 pandemic.
The UK has a current population of 68.5 million in 2022, with an average annual rate of population change of 0.4 per cent compared to India’s 0.9.
The average fertility rate for the entire world’s population in 2021 was 2.3 births per woman over her lifetime, down from over 5 in 1950.
By 2050, it is predicted that global fertility would have further decreased to 2.1 births per woman.
In a statement, UN Secretary-General António Guterres said, “This is a chance to celebrate our variety, recognize our shared humanity, and marvel at advances in health that have extended lifespans and substantially lowered maternal and child death rates.”
But a growing population was a reminder of a shared responsibility of care for the planet and to ‘reflect on where we still fall short of our commitments to one another,’ he added.
The UN research noted that the Covid-19 pandemic, which is projected to have killed 14.9 million people between January 2020 and December 2021, was mostly to blame for the decline in the world’s life expectancy at birth, which dropped from 72.8 years in 2019 to 71 years in 2021.
According to the United Nations, eight nations — the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and the United Republic of Tanzania — would account for more than half of the expected rise in the world’s population up to 2050.
Countries of sub-Saharan Africa are expected to contribute more than half of the increase anticipated through 2050.
However, between 2022 and 2050, a reduction in fertility is anticipated to lead to a 1% or more decline in the population of 61 countries.
The population increased from seven to eight billion individuals in roughly the same period of time—12 years—as it did from six to seven billion. This was one of the report’s other key findings.
It will take roughly 14.5 years to reach the next billion people by 2037.
Asia’s demographic growth was responsible for half of the ninth billion people that were added to the global population. Africa contributed about 400 million, which was the second-highest amount.
Ten countries contributed to more than half of population growth leading from the seventh to the eighth billion. India was by far the largest contributor, followed by China and Nigeria. Africa and Asia will drive population growth until the 9th billion is achieved in 2037.
In countries or regions where the lifetime fertility rate is less than 2.1 children per woman, two-thirds of the world’s population now resides (also known as replacement fertility).
A nearly nine-year rise since 1990, the average life expectancy at birth in 2019 was 72.8 years.
But in 2021, the life expectancy in the least developed countries fell seven years short of the global average. In many emerging countries, the proportion of people between the ages of 25 and 64 who are employed has increased.
