If real GDP rises by 5 percent and population rises by 7 percent, what is the likely effect on per capita real GDP?
Answer and explanation
Correct answer: It will fall
Per capita real GDP equals real GDP divided by population. If real GDP rises by 5% but population rises by 7%, the denominator grows faster than the numerator. Using the approximate growth rule, per capita real GDP changes by about 5% − 7% = −2%. Thus, it is likely to decline, even though total real GDP has increased. This comparison assumes other measurement conditions remain unchanged.
