Outline of the competition

The objective of this inaugural competition is to create the most accurate prediction for Japan’s Upper House Election on July 21 (Sun), 2019. Teams may use any publicly available data to create models that predict the parties’ vote shares for the proportional representation tier and the election outcome for candidates in the district tier of the election. The winners will be determined by the accuracy of the predictions and the evaluation of the prediction model by a panel of judges. Forecasts must be submitted before the polling day.

Teams are encouraged both to study and learn from well-established theories and methods of electoral forecasting, and to innovate using their own original ideas and hypotheses.

61 student teams with a total of 200 members have entered the competition. The top teams will be invited to present their models and methods in front of a panel of judges, with the grand prize and other prizes to be awarded to the best performing teams. In addition, all teams will give a poster presentation, and a poster prize will be determined mainly by popular votes from the audience.

The event will be held in both Japanese and English, with each team presenting their work in their preferred language.
