The global population hit 8 billion people in November 2022. Around which year did it hit 1 billion people?
A 1700
B 1800
C 1900
It took all of human history up to around 1803 or 1804 to reach the first billion people, then just over a century to hit 2 billion people in 1927. Then 33 years to hit 3 billion people in 1960. However, while the population continues to grow, the rate has slowed since the early 1960s, partly due to falling fertility rates. Countries with declining populations include Italy, Japan, Greece, and Latvia.
Correct Answer: 1800
