A new UC Davis study finds more than half of all California voters are voting by mail.
Breaking down the numbers: Voters in Southern California were more likely to go to the polls than in Northern California - where voting by mail is more popular.
The study found that younger voters were less likely to vote by mail, and are slower to adapt to voting by mail, than all other age groups.
In fact, it appears the older you are, the more likely you are to vote by mail in California.
However, more than 52% of young voters in Sacramento County voted by mail, the highest rate of any region in the state.
