I have no idea what that means. Statistically young people don't vote. I think its close to around 6% of 18-24 year olds vote in presidential elections with a statistically insignificant amount voting in other elections.
I don't know where you got those numbers from. The lowest I can find is in the 30% range for a presidential election. It's a bit disingenuous to write that off completely.
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.
You are confused about the difference between percentage of youngsters who vote, which is 40%, and the percentage of the total vote that are youngsters, which is 9%. But 18-24 is probably only 10% of the voting population.
Not quite. They do not vote on "old people". Why? Anything from simply age to not feeling older people understand their world and situation.
