The three younger generations – those ages 18 to 53 in 2018 – reported casting 62.2 million votes, compared with 60.1 million cast by Baby Boomers and older generations. But it’s not the first time—younger generations outvoted their elders 2016 presidential election as well.
Millennials and Gen X together cast 21.9 million more votes in 2018 than in 2014. (The number of eligible voter Millennials and Gen Xers grew by 2.5 million over those four years, due to the number of naturalizations exceeding mortality.) And 4.5 million votes were cast by Gen Z voters, all of whom turned 18 since 2014.
The number of eligible voters among Boomers and older generations fell by 8.8 million between the 2014 and 2018 elections, largely due to higher mortality among these generations.
Together, Gen Z and Millennials reported casting 30.6 million votes, a quarter of the total. Gen Z was responsible for 4.5 million, or 4%, of all votes. This post-Millennial generation is just starting to reach voting age, and their impact will likely be felt more in the 2020 presidential election, when they are projected to be 10% of eligible voters.
Millennials, ages 22 to 37 in 2018, cast 26.1 million votes, far higher than the number of votes they cast in 2014 (13.7 million).
