The Democracy Index is an annual publication by The Economist Intelligence Unit, aiming to measure the levels of democratic freedoms in 167 countries. It analyzes data including expert judgement, and public polling such as the World Values Survey. Countries ranking above 8 out of 10 are considered "full democracies" (the top 3 countries in 2021 were Norway, New Zealand, and Finland), Countries ranking under 4 are "Authoritarian regimes" (the 2021 bottom 3 countries were Afghanistan, Myanmar, and North Korea).
Ukraine's ranking in the Democracy Index has declined somewhat from 6.94 (a "flawed democracy") in 2006 to 5.57 ("hybrid regime") in 2021. Ukraine's next election, according to the constitution, is scheduled for 2024.
