In principle, how could a nation maintain a relatively high rate of economic growth even if it also has a relatively high rate of population growth?

An imbalance between births and deaths is the primary (and perhaps most obvious) cause of population growth.

According to the theory of economic growth, educated human capital can help a country's growth fortunes turn around. The difference between GDP growth and population growth is the pace of economic growth.

This equation looks to be slowing growth in a country with a shrinking population. This is not the case, since evidence from the country of SK shows that the amount of income spent on education by the population is a true factor of progress.

In this respect, if country SK's population declines or migrates to other countries, the country's economic growth will decline. These people raise the country's overall productivity, and as a result, the country's long-term real GDP growth will be zero.
