Brazil’s presidential elections captured global attention in late 2014. Events such as the sudden death of front running candidate in an airplane crash to a “second round” of elections when the first round wasn’t won by a sufficient margin created international speculation about the next leader for the world’s eighth largest economy. But another drama was playing out behind the scenes: an unexplained spike in voter turnout of over six million people.

Voting is mandatory in Brazil, beginning at age 18. But a mysterious swelling in voters from the 2010 elections to 2014 cannot be explained by immigration or aging population. Brazilian officials and political scientists cannot explain a spike in voter turnout of over six million people, primarily in the 25-69 age bracket.
