This video shows the occurrence of democracy protests around the world between 1989 and 2011. Solid dots indicate that a country experienced a democracy protest, while hollow dots indicate that at least one neighboring country within 50 km experienced at least one such protest during the last 90 days. Dot diameters are proportional to the square root of a protest’s size.
