Sadly, the way babies are being continually aborted, not going to happen.
how long did it take to double from 3 billion to 6 billion
With a 2009 rate of natural increase in Mexico of 1.13%, its population would be expected to double in ~61 years.
It took approximately 123 years for the world's population to double from 3 billion to 6 billion, from 1960 to 1983.
100 years
Depends on how much power thirst you drink.
mankind's don't need time to double the size. becauze they are very fast in doubling the population.
Since the population doubled for the first time, it would take the same amount of time to double a second time if the rate of growth remains constant. This is known as the doubling time and it depends on the population growth rate.
The Rule of 70 is a quick way to estimate how long it takes for a population to double in size based on its growth rate. To use the Rule of 70, divide 70 by the annual growth rate of the population. The result will give you approximately the number of years it takes for the population to double.
African countries take longer to "double time" meaninh the time it takes for a county's population to double its number
The time it takes for a population to double in size can be calculated using the rule of 70, which states that you divide 70 by the percentage growth rate of the population. For example, if a population grows at a rate of 3% per year, it would take approximately 70/3 = 23.3 years for the population to double in size.
The world population reached one billion in 1804 and seven billion in 2012. That's a difference of 208 years.
The population will double when it reaches 100% growth, which is a 20% increase five times. Therefore, it will take 5 years x 5 = 25 years for the population to double.
