Replication Data for: Measuring Knowledge of Parties' Legislative Seat Shares

In this note we use two original surveys (including survey experiments) conducted the week before the 2015 elections in the United Kingdom and Denmark to explore the best method for measuring individuals' knowledge of the partisan distribution of legislative seat shares in multi-party democracies. The complete lack of such questions in the corpus of survey research on multi-party democracies is a testament to the skepticism that many survey researchers have about the feasibility of such complex questions. However, our data, which is the first empirical test of this skepticism, reveals little evidence of respondent frustration or high levels of non-cooperation with these questions. In addition, our survey experiments, which examine the usefulness of different question formats, make it clear that such questions should be framed in terms of the numbers of seats each party holds rather than shares or percentages of seats.
