A bar chart showing a shift since 2005: fewer people live in democracies, while autocracies and autocratising countries now account for a much larger share of the world’s population.

A line chart comparing democratic decline across countries. The US shows a faster early drop in democratic standards than peers, outpacing countries like India and Serbia, though Hungary and Turkey see deeper long-term declines.

Democracy is on the brink of a worldwide depression — with the US leading the decline. Civil rights and equality in the land of the free have fallen to the levels of the mid-1960s and freedom of expression is at its lowest since the 1950s.
