2025 DIMENSIONS
0–100Scores are estimates of political systems in a specific year, not judgments about a country’s people or culture.
The same measurement model is applied to each place and year, but historical context, state formation, conflict, and data uncertainty differ. Use these lines to find questions—not to substitute a number for country knowledge.
