Doubling population rate is however long it takes for a country's population to double - but calculation wise I THINK (not sure) [ (Immigration rate - emigration rate) + (Birth Rate - Death Rate) ]
check around site for a confirmation of the formula
What else can I help you with?
What is the doubling period of Indian population?
birth rate=22.22 births/1000 population death rate= 6.4 deaths/ 1000 population net population increasing rate NPIR = 15.82births/1000 population doubling period = ln 2/NPIR = ln 2*1000/15.82 =43.81 year
Took this entire time period for the population to double?
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.
What is the doubling time of china in 2011?
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.
What is Germany's population doubling time?
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.
If a population has a growth rate of 2.5 percent how long will it take to double?
To calculate the doubling time of a population with a growth rate of 2.5 percent, you can use the Rule of 70. The Rule of 70 states that you divide 70 by the growth rate to determine the doubling time. In this case, 70 divided by 2.5 equals 28. Therefore, it would take approximately 28 years for the population to double with a growth rate of 2.5 percent.
Is Slovakia population doubling?
The population of Slovakia is about 5,430,000.
What is the formula for doubling the bacteria growth rate every 2 minutes in 1 hours?
I think the question means to say that the growth rate is (double every 2 minutes).doubling interval = 2 minutes1 hour = 60 minutes = (60 / 2) = 30 doubling intervalsStarting with 1 bacterium and reproducing asexually (do bacteria do this ? What do I know. I'm only an EE.) . . . . .If all survive, then the population after doubling 30 times = 230 = 1,073,741,824 bugs.
Given a growth rate of 3 percent per year how long will it take for a population of 100000 individuals to double?
It will take approximately 23 years for a population to double with a growth rate of 3 percent per year. This can be calculated using the rule of 70, where you divide 70 by the growth rate to find the doubling time. In this case, 70 divided by 3 equals 23.33, which can be rounded to 23 years.
What is Japan's population doubling time?
289 years
How can one determine the order of a reaction from a table?
To determine the order of a reaction from a table, you can look at how the rate of the reaction changes with the concentration of reactants. If doubling the concentration of a reactant doubles the rate, the reaction is first order with respect to that reactant. If doubling the concentration quadruples the rate, the reaction is second order. And if doubling the concentration increases the rate by a factor of eight, the reaction is third order.
How long did it take for the population to double a second time?
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.
What is Brazil's population doubling time?
43 years.
