How would I asses the balance of power? why is it in this way?

The balance of power is very unbalanced as the majority of panelists are males and there are 3 times as many men on the top 100 to woman. This could be a result of modren society where men are mostly dominant and have more control in media. Woman have smaller roles and are less important in media.
