Turns out I was wrong. Youngsters aren't 6% of the vote, but closer to about 9%. Still tiny though. The data indicates people who are registered voters are about twice as likely to become a voter after the age of 25.
If you mean table 3, make sure you read the following associated quoted part:
"This statistic is affected by two factors: youth turnout and the age structure of the whole population. (Youth share could rise, for example, if turnout remained constant but
the population became younger.)"
Also, my quoted data is from 18-29, and approx 40-51%. If 18-24 is only 6-9% then the group from 24-29 is either far smaller, or is having some really insane turnout of more than 71%.
