The article compares gender wage gaps in different job types in Finland's private sector. By looking at data from 2002 to 2009, the researchers found that factors specific to each sector play a big role in these wage gaps.

This means that simply comparing overall wage gaps might not give the full picture of why men and women are paid differently.
