A survey suggests a link between women's wages and their decisions whether or not to have children.

A Korea Development Institute report says a ten percent pay increase lowers the chances that a woman will choose to have a first baby by two-and-a-half percent and a second baby by two-point-seven percent.

Higher wages for men, however, were found to increase their odds of deciding to have children. If men receive a ten percent raise, they are three-point-two percent more likely to decide to have a second child.

The state-run institute says that pay increases for working women are partially to blame for the drop in second child births between 1980 and 2005.

The survey is an analysis of the 2006 birthrate on over 66-hundred married Korean women.
