World population just passed 8 billion
Throughout history, each new billion people has arrived faster than the previous billion.
So how did we get here and what has global population growth looked like historically?
As these charts show, it took humans a while to hit our first landmark of 1 billion people in 1803. This was largely facilitated by the many advances made during the second industrial revolution that began in the 1700s.
Since then, rising fertility rates and continuing developments in medicine and agriculture have allowed the global population to increase rapidly. But, due to shifting demographics and declining fertility rates, the rate of growth has been slowing for some time.
These will be the world's most populous countries by 2030
India's population is set to rise to 1.515 billion in 2030 from 1.417 billion in 2022, which is set to make it the world's most populous country in 2030 according to the latest edition of the United Nations' World Population Prospects.
China (1.426 billion) is currently just in front of India (1.417 billion) with the world's largest population, but the two countries remain significantly ahead of the rest – no other nation will surpass 360 million as we move into the next decade.
