World’s Population To Hit 8 Billion This Week—Here’s What You Need To Know

World’s Population To Hit 8 Billion

The UN projected that the world's population is projected to reach 8 billion people on Tuesday - 15th November 2022. They called this a milestone in human development.

The milestone comes just 11 years after the human population reached 7 billion in 2011. The international body attributed the rise in population to a gradual increase in human lifespan due to improvements in public health, nutrition, personal hygiene, and medicine.

The annual World Population Prospect report, also notes that the global population is growing at its slowest rate since 1950, having fallen to less that one per cent in 2020.

While it took the global population 11 years to grow from 7 to 8 billion, the latest projections by the UN suggest it will take approximately 8 years - until 2030 - for the global population to grow around 8.5 Billion and 15 years - until 2037 - for it to reach 9 billion, 9.7 billion in 2050 and 10.4 billion in 2100, a sign that the overall growth rate of the global population is slowing.

Birth rates have fallen across much of the world—numerous factors can help explain this, including increased access to contraception, the aging population, better education and progress protecting the rights of women and children—and in many countries, fertility rates have already fallen well below what is needed to maintain the size of the population, reports Forbes.

Growth will not happen evenly across the planet; the UN projected that more than half of the increase in global population up to 2050 will be concentrated in just eight countries: the Democratic Republic of the Congo (DRC), Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.

Along with this, there are few other significant changes that we will notice:

  1. The UN said, in particular increasing life expectancies—slated to rise from 72.98 in 2019 to 77.2 in 2050—and markedly older populations.

  2. The proportion of people aged 65 will rise from 10% in 2022 to 16% in 2050.

  3. India will overtake China as the world’s most populous country at some point during 2023, the UN estimated. India and China are currently home to around 1.39 billion and 1.41 billion people. The UN projects India and China will remain the world’s first and second largest population hubs, though China is expected to face a precipitous drop in its population, halving its current value by the end of the century.

  4. By 2050, the U.S. will no longer be the world’s third most populous country, the UN estimates. It will sit in fourth place behind Nigeria with around 375 million people, the agency projected.


It is impossible to know the precise population of any given moment. The UN’s figures are based on models designed using census and other demographic data. Most forecasts suggest the global population will decline in the latter half of the century, though the further out forecasts go the less reliable their predictions are.
