The poll, conducted by the Harvard Institute of Politics, found 40 percent of those aged between 18 and 29 said they would “definitely vote” in the upcoming elections.
Of those young people who say they will definitely vote 66 percent said they plan to back Democratic candidates, versus 32 percent for the Republicans.
President Trump’s approval rating amongst young Americans sits at just 26 percent.
This is significantly below the figure for US adults as a whole, which sits at 44 percent according to a recent Gallup poll.
Referring to youth turnout John Della Volpe, who helped coordinate the research, said: “I’m pretty confident it will surpass anything we have seen since 1986.
“There is a tremendous amount of passion and energy.”
Youth turnout in US midterms since 1986 has peaked at 21 percent, which was achieved in both 1986 and 1994.
Jessica Cohen, a 30-year-old California based product manager, commented: “There’s an embarrassment that comes with having not voted, or having not cared about voting in the past.
“People are realising how many consequences there have been since 2016.”
Data available from a number of states shows a dramatic increase in early voting amongst young people.
Both Texas and Georgia have seen turnout amongst those aged 18-28, at this stage in the election, increase by at least five times compared to the last mid-term elections in 2014.
In Texas, the young voting figure is up 508 percent, versus 476 percent for Georgia.
The election for a seat representing Texas in the Senate is expected to be especially close, with Trump supporting Republican incumbent Ted Cruz facing off against Democrat Beto O’Rourke.
Data journalist Elliott Morris commented on the high turnout tweeting: “Can’t believe how crazy this level of engagement is for a midterm.”
Increased youth engagement could also have a dramatic impact on the 2020 Presidential election.
Should he run again, just 11 percent of those aged between 18 and 29 said they were “sure” to reelect Trump versus 59 percent who claimed they would “never vote for him”.
