Democracy is in retreat, according to the latest edition of the Democracy Index from our sister company, The Economist Intelligence Unit (EIU). This annual survey, which rates the state of democracy across 167 countries based on five measures—electoral process and pluralism, the functioning of government, political participation, democratic political culture and civil liberties—finds that democracy has been eroded around the world in the past year. The global score of 5.44 out of ten is the lowest recorded since the index began in 2006. Just 22 countries, home to 430m people, were deemed “full democracies” by the EIU. More than a third of the world’s population, meanwhile, still live under authoritarian rule.
