It's a Group Thing: How Voters go to the Polls Together

Across European Parliament, local and general elections in Denmark between half and three quarters of voters in households with multiple voters cast their vote within a minute of another household member. This finding, revealed using data from a time-stamped voter panel covering more than two million Danish voters, establishes that many families visit the polling station together. The result are replicated using survey data from Denmark, the UK and a range of other countries, indicating that voting together is a widespread phenomenon, supporting the characterization of voting as a social act. For the first time our analysis reveals that acquiring a potential voting partner increases turnout, whilst losing one decreases turnout.
