The polity is always fully governed*

Just discovered @MaxCRoser and his incredible data visualizations.  Here’s one showing how democracy, autocracy and colonialism has changed over the last 100 years:

(note: The figure doesn’t scale very clearly; here’s a link to a Washington Post article about it with much larger and clearer graphic.)

It’s amazing what a small percentage of the world’s population lived in a democracy in 1900 (around 10%).  Thankfully that number climbed significantly over the century.

*except for the small percentage listed as “no data”! The “no data” category disappeared around mid-century and is making a comeback.  I’m curious what “no data” means and why it’s on the rise. Would Yemen qualify?
