Figures are drawn from V-Dem Institute / various. We use this source because it produces a single, internally consistent dataset rather than aggregating from national statistics offices, which makes year-on-year comparison reliable. The next update is expected when the source publishes its next annual release — see the methodology section below for which year of data is currently shown.
