When I plug in population densities and fertility values of various countries from Wikipedia, the Spearman's correlation coefficient of the two variables is roughly 0.26.

From that, I gather that population density is a contributing factor (perhaps due to its relationship with cost of living) but not enough to explain the whole story behind what's going on in South Korea.
