The world population has doubled from 1974 to 8 billion people.

The two most populated areas in the world in 2022 were both in Asia: Central and Southern Asia had 2.1 billion people while Eastern and South Eastern Asia had 2.3 billion. The largest populations in these areas were India and China, both with a population of more than 1.4 billion.

According to United Nations predictions, the world’s population will surpass 8 billion people on November 15, 2022. According to the most recent estimates made by the international organization, the world’s population might reach 8.5 billion in 2030, 9.7 billion in 2050, and 10.4 billion in 2100.

The annual World Population Prospect Report also states that, having decreased to less than 1% in 2020, the pace of population growth worldwide is at its lowest level since 1950.

It took 12 years for the world’s population to increase from 7 billion to 8 billion, but it will take around 15 years, or until 2037, to reach 9 billion, indicating that the population’s general growth rate has been decreasing.

Key Highlights when the world population surpasses 8 billion

  1. Eastern and South Eastern Asia, with 2.3 billion people, and Central and Southern Asia, with 2.1 billion people, were the two most populated areas in the world in 2022. The largest populations in these areas were India and China, both with a population of more than 1.4 billion.
  2. Just eight nations—Egypt, Congo, Ethiopia, Nigeria, India, Pakistan, Tanzania, and the Philippines—will account for more than half of the predicted rise in global population by the year 2050.
  3. According to UN projections, India will overtake China as the world’s most populous nation in 2023.
  4. Rising per capita incomes are the primary cause of unsustainable patterns of production and consumption, despite the fact that population increase amplifies the environmental effects of economic development.

Why is the world’s population increasing?

Population expansion is fueled in part by lower mortality rates, which are reflected in increasing life expectancy at birth.

Globally, life expectancy reached 72.8 years in 2019, an increase of about 9 years from 1990. Furthermore, mortality decreases are expected to result in an average world lifetime of roughly 77.2 years by 2050.

Countries with the greatest fertility rates have the lowest per capita income. As a result, the global population has grown more concentrated among the world’s poorest nations, the majority of which are in Sub-Saharan Africa.

As the world’s population approaches 8 billion, India’s population growth slows.

As the world population approaches 8 billion, India, which was once a key engine of global population growth, is slowing.

Falling fertility rates in South Asian countries have prompted at least one state to reconsider regulations that encouraged families to have no more than two children.

The UN estimates that the world’s population has reached 8 billion people, with China and India accounting for more than a third of the total. India’s population is estimated to be 1.38 billion, slightly less than China’s population of 1.4 billion, according to the World Bank.
