Women In The Boardroom

In an attempt to address the lack of females in decision-making positions in companies, many countries have introduced mandated quotas for boardroom membership. Norway became the first country in the world to introduce a female boardroom quota and it has proven extremely successful. Today, women account for 39 percent of Norwegian boardrooms, a figure that has been consistently higher than other developed countries. The U.S. has some catching up to do with women accounting for only 12 percent of boardroom membership.
