The time it takes for a population to double is known as the doubling time. It is calculated using the rule of 70, which states that you divide 70 by the growth rate to find the doubling time. For example, if a population is growing at a rate of 2% per year, it would take approximately 35 years for the population to double.

The population of Slovakia is about 5,430,000.
Japans population is just over 127 million
Germany and other European countries' natural growth rate is actually negative (on average, women in Germany give birth to 1.5 children, which is below the number to yield zero population growth, approximately 2.1 children). Germany's natural growth rate of -0.1 can not be used to determine doubling time because the population is actually shrinking in size.
The doubling time is around 26 minutes.

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.
mankind's don't need time to double the size. becauze they are very fast in doubling the population.
Sadly, the way babies are being continually aborted, not going to happen.
