Voter turnout in the United States presidential elections
Recent decades have seen increasing concern over the fact that youth voting turnout is consistently lower than turnout among older generations. Several programs to increase the rates of voting among young people—such as MTV's "Rock the Vote" (founded in 1990) and the "Vote or Die" initiative (starting in 2012)—may have marginally increased turnouts of those between the ages of 18 and 25 to vote. However, the "Stanford Social Innovation Review" found no evidence of a decline in youth voter turnout. In fact, they argue that "Millennials are turning out at similar rates to the previous two generations when they face their first elections."
Voter apathy
Voter registration in the United States is an independent responsibility, so citizens choose whether they want to register or not. This led to only 64% of the voting age population being registered to vote in 2016. The United States is one of the sole countries that requires its citizens to register separately from voting. The lack of automatic registration contributes to the issue that there are over a third of eligible citizen in the United States that are not registered to vote.
