World Population to strike 8 billion: The world’s population is expected to reach the 8 billion threshold on November 15, 2022, according to the UN. India now has a population of 7,999,959,816 people, and according to the World Population Prospects 2022 report, it will overtake China as the most populous nation by the year 2023.
World Population to strike 8 billion: Key Points
- It was made public on World Population Day. Additionally, a 10.4 billion worldwide population peak is anticipated in the 2080s.
- The United Nations predicted, global population growth has slowed to its smallest rate since 1950 and will reach just 1% by 2020.
- According to the UN, the population of the globe could increase to 8.5 billion in 2030 and 9.7 billion in 2050.
- The UN predicted that by the 2080s, the world population would reach the 10.4 billion milestone and would stay there until 2100.
- UN notified about the data findings about the world’s population while also emphasising the need to establish a balance between sustainable development and population growth.
- The annual World Population Prospect study, which was made public on Monday to coincide with World Population Day, also observes that the rate of population growth worldwide is slowing down and will reach less than 1% in 2020.
- While it took 12 years for the world’s population to increase from 7 to 8 billion people, it will take roughly 15 years—until 2037—for it to reach 9 billion people, indicating that the population’s overall growth rate is slowing.
Decrease in fertility rate in Few Nations:
According to World Population Prospects 2022, fertility has significantly decreased in recent decades for several nations.
- Currently, two-thirds of the world’s population reside in nations or regions with lifetime fertility rates below 2.1 children per woman.
- Given the low levels of fertility, it is predicted that the population of 61 countries or regions will decline by 1% or more between 2022 and 2050. In other instances, as a result of the high emigration rates.
- Notably, the UN has also predicted that the world’s population will rise until 2050 and will be concentrated in eight nations.
- The 8 Nations are: Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, Philippines and Tanzania.
- The nations with the lowest incomes per capita also tend to have the highest fertility rates.
- As a result, the world’s poorest nations, the most of which are in sub-Saharan Africa, have seen an increase in their share of the global population over time. The Sustainable Development Goals (SDGs), which remain the world’s best path toward a happy and healthy future, can be thwarted in these nations by continuing high population increase.
World Population and Per Capita Income:
- Rising per capita incomes are the primary cause of unsustainable patterns of production and consumption, despite the fact that population increase compounds the environmental effects of economic development.
- Countries whose income per capita is higher tend to have higher per capita resource consumption and greenhouse gas emissions than those where the population is more densely populated.
