A 17-word Facebook reminder contributed to substantial increases in online voter registration, top election officials said.
At least nine secretaries of state have credited the social network's voter registration reminder, displayed for four days in September, with boosting sign-ups, in some cases by considerable amounts. Data from nine other states show that registrations rose drastically on the first day of the campaign compared with the day before.
"Facebook clearly moved the needle in a significant way," Alex Padilla, California's secretary of state, said Tuesday.
In California, 123,279 people registered to vote or updated their registrations Sept. 23, the first day that Facebook users were presented with the reminder. That was the fourth-highest daily total in the history of the state's online registration site.
Indiana similarly recorded its third-highest daily online registration total ever. Minnesota, meanwhile, broke its record for the most online voter registrations in a single week, thanks at least in part to the Facebook campaign, which continued through Sept. 26.
Those were among the nine states where election administrators extolled the social network in official statements. In nine others, online registration rose as Facebook began its effort, according to a review of data collected by the nonprofit Center for Election Innovation & Research. In those states, registration increased anywhere from two- to 23-fold on the first day the reminder went up, compared with the previous day.
Facebook's effort is notable not just for boosting voter registration but also for the kinds of voters it may have helped to enlist. While Facebook could not provide demographic breakdowns of the users who registered, the social network is more popular among female internet users than male users, and the same is true for young users compared with older users, according to 2015 data from the Pew Research Center. Both groups — women and younger adults — tend to lean Democratic.
In California, for example, nearly 24 percent of online voter registrations during the Facebook campaign came from residents ages 17-25. Nearly 30 percent more came from Californians from 26 to 35 years old.
