Analysis reveals socioeconomic status shaped vote distribution among parties in a hung parliament situation in Japan.
In the 50th Japan House of Representatives election, the Liberal Democratic Party (LDP) lost a large number of seats, dropping below a majority in the House of Representatives, and the diet was put into a state of hung parliament.This was due to the increase in votes received by the opposition parties against the LDP.In this study, regional data was analyzed on the number of votes received by the opposition parties against the LDP.As a result, a correlation was confirmed between people's socioeconomic status, such as age, educational background, occupation, and income, and the vote share of each political party.Furthermore, age, educational background, and occupation had an influence on the number of votes received by the opposition parties against the LDP.Specifically, in areas with many people who have completed higher education and areas with a large white-collar population, the opposition parties increased their votes against the LDP, while in areas with a large elderly population, they did not increase their votes.In addition, the influence of age was stronger in the 50th data compared to the 49th.
