Fact Sheet: Unprecedented voter turnout for the general election

Eligible voter turnout at 71%, compared to 62% in 2016

November 13, 2020 – Silicon Valley’s eligible voter turnout for the November 3 General Election, based on results reported to-date, was at unprecedented levels. Preliminary numbers suggest an eligible voter turnout of 71 percent, compared to 62 percent in the 2016 General Election. “We haven’t seen a turnout like this in at least 50 years, if ever,” said Joint Venture’s Institute for Regional Studies Director of Research, Rachel Massaro. “The 2016 and 2008 Presidential General Elections both saw turnout at around 62 percent. But other than those, our region has never seen a number above 60 percent.” *References to Silicon Valley include Santa Clara and San Mateo Counties combined.*

Likewise, San Francisco voters turned out for the election at record levels. Preliminary eligible voter turnout for the 2020 General Election indicates approximately 67 percent — two percentage points higher than the 2008 Presidential General Election, and three percentage points higher than the 2016 eligible voter turnout of 64 percent.

Preliminary absentee voting rates are also higher than ever before, due in large part to the pandemic. In San Mateo County, 92 percent of ballots cast were either sent by mail, dropped off in a ballot box, or hand-delivered to a polling location. This compares to a rate of 72 percent in the 2016 Presidential General Election, and has been exceeded only once (in the 2018 Statewide Direct Primary Election for which around 160,000 county residents voted absentee – less than half of the more than 334,000 counted in this election thus far). In San Francisco, the preliminary absentee voting rate stands at 91 percent. The Santa Clara County unofficial election results posted yesterday do not include a vote-by-mail total; however, based on early voting totals alone, the absentee voting rate will definitely exceed 79 percent (and will likely be much higher).

The most up-to-date reporting indicates that 74 percent of Silicon Valley voters cast ballots for Joe Biden – the same share that cast votes for Hillary Clinton in 2016. Likewise, 85 percent of San Francisco voters, 76 percent of Bay Area voters, and 64 percent of California voters cast ballots for Biden (compared to 85, 74, and 62 percent, respectively, in 2016).
