A country's total growth rate is 0.7 percent while its natural increase rate is 1.8 percent. What is the net migration rate?

Answer and explanation

Correct answer: -1.1 percent

Net migration shows the balance between people entering and leaving a country. It is positive when immigration is greater than emigration and negative when more people leave than enter. Total population growth is made up of natural increase plus net migration, so the two rates must be compared carefully.

Here, total growth is 0.7 percent and natural increase is 1.8 percent. Therefore, net migration is calculated as \(0.7-1.8=-1.1\) percent. The negative sign means that migration reduced the population growth rate; outward migration was greater than inward migration. Thus, option B is correct. Option A reverses the subtraction and gives the wrong sign.
