Where registration rates have improved — and gone south

The good news for almost all counties is that they increased their voter registration rate since the 2016 general election — with one notable exception. San Francisco’s registration rate decreased by 1 percentage point to 78% this election cycle. Tiny Alpine County, however, outdid the rest of the state when it reported the biggest increase, jumping 18 percentage points from 76% to 94%. Among large counties, San Bernardino shifted the most, jumping 15 percentage points from 68% to 83%.
