Question

Suppose a country's per capita GDP falls 0.4% even though its GDP grows by 1.7%. From this it can be determined that its population grew by_____%.

Answer 1

The population grew by 2.1% if a country's per capita GDP falls by 0.4% while its total GDP grows by 1.7%.

Step-by-step explanation:

If a country's per capita GDP falls by 0.4% while its total GDP grows by 1.7%, we can calculate the rate at which the population has grown by using the following relationship: the total GDP growth rate is the sum of the per capita GDP growth rate and the population growth rate.

To find the population growth rate, we rearrange this relationship to isolate the population growth rate.

The calculation is as follows:

Total GDP Growth Rate = Per Capita GDP Growth Rate + Population Growth Rate

1.7% (Total GDP Growth) = -0.4% (Per Capita GDP Growth) + Population Growth Rate

Population Growth Rate = 1.7% + 0.4%

Population Growth Rate = 2.1%

Therefore, it can be determined that the population grew by 2.1%.
