Gross migration is the total flow of migrants across a border, i.e. in-migrants + out-migrants, or in the case of international migration, immigrants + emigrants.
How do you calculate migration rate?
- Step 1: subtract immigration rate from emigration rate.
- Step 2: divide result by 1000.
- Step 3: multiply result by 100.
- Natural increase (more births than deaths)
- Step 1: divide the number of people emigrating from a country by a country’s total population.
- Step 2: multiply the result by 1000.
What is the formula of calculation of out migration rate?
For this reason, it is generally preferred to calculate two separate crude migration rates: Crude In-migration rate (I/P * 1000) and Crude Out-Migration rate (E/P * 1000).
How do you calculate net migration growth rate?
It is calculated by dividing the number of people added to a population in a year (Natural Increase + Net In-Migration) by the population size at the start of the year. If births equal deaths and there is zero net migration, the growth rate will be zero.
Which country has the lowest net migration rate?

What is the formula for population mean?
The formula to find the population mean is: μ = (Σ * X)/ N. where: Σ means “the sum of.” X = all the individual items in the group.
What is growth formula?
The formula used for the average growth rate over time method is to divide the present value by the past value, multiply to the 1/N power and then subtract one. “N” in this formula represents the number of years. [Growth rate = (Present value / Past value) 1/N – 1]
