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."
Youth suffrage
A proposal to lower the voting age from 18 to 16 was defeated in the Venezuelan constitutional referendum, 2007.
Demeny voting is the idea that parents would cast votes on behalf of their children thereby ensuring that the interests of children were properly accounted for in the voting system. Most young people do not support themselves financially and are reliant upon parents for support, thus parental voting power should be proportionate to the number of dependents, especially where government benefits are concerned, to appropriately counterbalance the interests of the childless. Essentially, a case for "no taxation without representation." However, as children and their parents often have differing political, social, and economic interests, it is doubtful demeny voting would result in any significant advances of youth interests in government.
