Not long ago, the election of a woman as head of state or chief executive of a large corporation would generate headlines around the world. Today, no one is surprised to see women leading governments, companies, universities or other institutions.

In fact, gender equality has advanced so far that we've been wondering: Is there anything left that has never been run by a woman?

We want to know—but we need your help. Man Planet is a crowdsourced list of institutions and organizations that have been led exclusively by men.

We're not sure how much interest there is in this topic, so we're releasing a very partial list to test the waters. Have a look and let us know what you think. And if we've missed anything, please add it to the list. It takes less than a minute, and no registration is required.

Man Planet is a work in progress created by Sociopúblico, a strategy and communications agency working with organizations that promote social progress around the world.
