The world population has reportedly surpassed an estimated 8 billion people, according to the UN Department of Economic and Social Affairs.
Nigeria is expected to have 216 million residents or 2.7% of the world’s population.
This was stated by the UN in its most recent World Population Prospects 2022, which was published on Tuesday in honour of World Population Day.
The Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and the United Republic of Tanzania make up the majority of the projected population, accounting for more than half of the world’s population.
India would overtake China as the world’s most populous nation in 2023, it continued.
In 2020, the world’s population decreased by less than 1%, rising 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.
The research also notes that fertility rates have dropped significantly in several nations during the past few decades.
“As of now, two-thirds of the world’s population reside in regions or nations with lifetime fertility rates below 2.1 births per woman, or about the number necessary for a population with low mortality to have long-term growth of zero.
According to the analysis, persistent low levels of fertility and, in certain circumstances, high rates of emigration would cause the populations of 61 nations or regions to fall by 1 per cent or more between 2022 and 2050.
“Up until 2050, 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 anticipated rise in the world’s population.
Sub-Saharan African nations are forecast to generate more than half of the growth projected through 2050.
UN Secretary-General António Guterres stated, “This year’s World Population Day coincides with a landmark year when we expect the birth of the eight billionth person on the planet. This is a time to celebrate our differences, acknowledge our shared humanity, and be in awe of medical advances that have increased lifespans and significantly lowered maternal and infant mortality rates.
“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,” the author writes.
