In 2011, China's population doubling time was approximately 32 years. This means that based on the population growth rate at that time, it would take around 32 years for the population to double in size.

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.
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.
If the doubling time is 43 minutes, after 43 minutes the population will double in size to 2048 bacteria. So with an initial population of 1024 bacteria, after 43 minutes it will double to 2048.
The doubling rate refers to the time it takes for a quantity, such as a population or an investment, to double in size. It is often expressed in terms of years and is a useful metric for understanding growth rates. For example, if a population has a doubling rate of 10 years, it means that under current growth conditions, it will take 10 years for the population to grow to twice its current size. This concept is commonly used in fields like demography, finance, and economics.
mankind's don't need time to double the size. becauze they are very fast in doubling the population.
