Eligible Voter Turnout, by Age

Santa Clara & San Mateo Counties | 2016 & 2020 Presidential General Elections

Eligible Voter Turnout by Age data are from the Center for Inclusive Democracy at the USC Sol Price School of Public Policy, using data from the Statewide Database (the Redistricting Database for the State of California) and California Department of Finance (for voting age population estimates). Silicon Valley includes Santa Clara and San Mateo Counties. Eligible voter turnout is defined as the percentage of adult citizens who voted. 2016 General Election turnout for California does not include Yuba County. The eligible turnout rate in San Francisco increased significantly in 2020 due to an estimated decline in the citizen voting age population ages 25-34.
