A recent study from the University of California, Davis found that after online voter registration became available in the state on September 19, 2012, approximately half of all voter registrations came via this method.
Voters ages 18-24 took greatest advantage of the new online system. Of the more than 244,000 new young registrants for the November 2012 election, more than 154,000, or 63 percent - registered online. This age group made up 30 percent of the more than 500,000 new online registrants.
Additionally, there are now two million young registrants in California, an increase of 13.9 percent since November 2008.
