How it worksPolitical system: Multiparty parliamentary electoral system; coalition labels and constituent organizations are separate.
Selected nationally significant organizations and contrasting policy traditions. This is not an exhaustive register or a current seat/coalition chart. Profiles without independently supported positions remain unplotted.
No stable internal ideological group is assigned its own score without independently reviewed evidence. Leadership rivalries, predecessor parties and electoral partners are not automatically treated as factions.

How to read these estimates
Scope. The original population-ranked top 50 plus Israel, Taiwan, New Zealand, EU/EFTA states, selected American democracies and Serbia, Georgia, Armenia and Moldova. Closed/noncompetitive regimes retain profiles/context only. Inclusion is not a democracy rating. Taiwan population is a separate official household-registration count and has no World Bank population rank. Population data use the World Bank snapshot retrieved 2026-10-18; Taiwan’s separately sourced household-registration count has no World Bank rank. Selected nationally significant parties and documented factions are included, with gaps explained by country. This is not an exhaustive party register or a claim that every included system is a full democracy.
Chart eligibility. Closed dictatorships, military/theocratic rule and explicitly reviewed noncompetitive regimes have profiles and context only, with no chart or embeddable diagram. Competitive but flawed electoral systems remain included. The dated eligibility sources are separate from ideology estimates; V-Dem’s 2025 regime baseline is supplemented by documented current-evidence exceptions.
Economic axis. Left emphasizes redistribution, social provision and public ownership; right emphasizes private ownership, competition and lower state economic intervention. Social axis. Progressive emphasizes individual autonomy and equal treatment across social groups; traditional emphasizes inherited institutions, religious-social norms and cultural continuity. These dimensions can overlap and cannot capture every issue.
Placement. Whole-number coordinates from −5 to +5 are editorial judgments based on the linked programs and country research, not survey results, validated measurements or an average of every member’s views. Zero means a mixed or central estimate. Null means the evidence does not establish both dimensions; those profiles remain available without a point. Treat small differences as inconclusive.
Factions. Dashed squares identify internal groups or policy currents. Some cross-party camps are profiled with their affiliation stated explicitly. Groups can overlap. Personality networks are not assigned separate ideological scores without evidence. The absence of a faction means coverage is unestablished, not that the party is internally uniform.
Politicians. Diamond markers identify independently sourced individual placements, linked to their existing profiles. They are shown only where a review is available and are never assigned their party’s coordinates automatically. The politician layer can be switched off independently.
Limits and dates. Source publication dates and profile review dates are separate. BTI 2026 reports principally assess 2023–early 2025; later primary statements are linked where reviewed. These are present-day editorial interpretations of the available evidence, with older evidence identified. Party status and policies can change. Neither coordinate measures democracy, authoritarianism, popularity, vote share or the views of a country’s population.
