Let's figure out these population doubling times.

A) one billion to two billion

Identify the years when the population reached these milestones.

The world population reached two billion around 1927.
Calculate the difference in years.
1927 - 1804 = 123 years

B) two billion to four billion
Identify the years when the population reached these milestones.
The world population reached two billion around 1927.
The world population reached four billion around 1974.
Calculate the difference in years.
1974 - 1927 = 47 years
