How does government type actually correlate with governance outcomes?
The Civica Index does not bake bonuses or penalties into government types. Instead, we publish what the data says: average CI, distribution spread, and long-run trajectory per category — so you can see whether any government type systematically produces better outcomes, or whether individual countries matter more than their system.
This lens uses published accountability categories. Because the regime classes are already the normalized endpoints, rows stay flat rather than expanding into subtypes.
Structural form answers what the system is: parliamentary republic, constitutional monarchy, directorial republic, and related forms.
Regime type answers how executive-legislative accountability works in the Bjornskov-Rode / CGV tradition: parliamentary, semi-presidential, or presidential democracy, plus civilian, military, or royal dictatorship.
These lenses can disagree for valid academic reasons. Switzerland, for example, can appear as a presidential democracy in the accountability sense while remaining a federal directorial republic structurally.
Each dot is a country.
Average, spread, and trajectory.
Parliamentary democracy tends to cluster at the top. Civilian dictatorship shows the widest spread.
The strongest family visible today averages 83.6 and bottoms out at 27. Civilian dictatorship spans 85 points, from 1 to 86. Expanding rows helps show whether that signal comes from one subtype or from the whole family.
“Parliamentary democracyare better.” The data only shows where systems cluster today.
The Civica Index does not argue that any single government type is best. Correlation is shown; causation is left to researchers and historians who can control for confounders that the Index cannot.
