Does online voting mobilize citizens who otherwise would not
participate? During the annual participatory budgeting vote in the southern
state of Rio Grande do Sul in Brazil—the world’s largest—Internet voters were
asked whether they would have participated had there not been an online voting
option (i-voting). The study documents an 8.2 percent increase in total
turn-out with the introduction of i-voting. In support of the mobilization hypothesis,
unique survey data show that i-voting is mainly used by new participants rather
than just for convenience by those who were already mobilized. The study also
finds that age, gender, income, education, and social media usage are
significant predictors of being online-only voters. Technology appears more
likely to engage people who are younger, male, of higher income and educational
attainment, and more frequent social media users.
