With the upcoming presidential election, there has been much talk about the prospect of electing the first female U.S. president. As the first female major party nominee, Hillary Clinton is the only woman in U.S. history to come this close to the presidency. (The first female major party candidate was Shirley Chisholm in 1972, and the first woman to announce her own candidacy for president was Victoria Woodhull in 1872.)

It's no secret that the United States is not as progressive as other major countries on this front. However, many people are not aware of just how behind we are. In fact, there are many so-called "third world" or developing countries that have or have had female leaders.

The United Nations has identified 48 nations as the world's least developed countries. These classifications are based on three criteria: gross national income per capita, the human asset index, and the economic vulnerability index. Despite these shortcomings in economic and social progress, fully 14 of these 48 countries (more than one quarter!) have or have had women leaders.
