A. 55,000 ; B. 45,000 ; C. 40,000 ; D. 35,000 Show how you get the answer.
To find the magnitude of net migration in country A during 1999, we need to subtract the total number of births and deaths from the total increase in population.
Net migration = Total increase in population - (Total number of births + Total number of deaths)
Net migration = 50,000 - (10,000 + 5,000)
Net migration = 50,000 - 15,000
Net migration = 35,000
Therefore, the magnitude of net migration in country A during 1999 is 35,000.
Answer: D. 35,000
