How this is calculated
Leadership Rating is a weighted average of 10 dimensions (weights listed on the Methodology page). Five dimensions use live World Bank indicators; Vision is derived from WIPO patents, Oxford AI Readiness, UNESCO tertiary enrolment, and tenure momentum; Communication is derived from GDELT media volume and tone, domestic approval, and a tone/approval crisis-resilience term, where coverage exists, otherwise shown as no data (still rolling out); Diplomacy has no data source yet; Crisis Management is derived from WB GDP shock data where tenure overlapped, otherwise curated. Popularity uses sourced survey data (EAP 3.0 globally; Afrobarometer R9 for Africa; Arab Barometer VIII for MENA) when available, otherwise a curated estimate. Political position uses V-Dem V-Party expert coding (v2pariglef, economic left–right) as its primary source where the leader's party is covered; otherwise shown as no data (archived 2016–2020 leaders instead carry a coarse leftist/centrist/rightist class from the Global Leader Ideologies dataset, never a numeric score).

How this is calculated
Five dimensions use live World Bank 2024 indicators: Governance (govEffectiveness), Economy (gdpGrowth), Integrity (controlOfCorruption), Politics (voiceAndAccountability), Defense (politicalStability). Vision is derived from WIPO patents, Oxford AI Readiness, UNESCO tertiary enrolment, and tenure momentum (the real change in those three since this leader took office). Crisis Management is derived from WB GDP growth during 2020 and 2022 shock years where tenure overlapped; otherwise curated. Communication is derived from GDELT media volume and tone (tone-gated reach), domestic approval, and a crisis-resilience term blending media tone with approval during the leader's highest-attention periods, where coverage exists — otherwise shown as no data (coverage is still rolling out across leaders); Diplomacy is overlaid from the Diplomatic Signal — a GDELT-derived proxy for the country's diplomatic engagement and cooperativeness (2.1 Events) plus how the leader's diplomacy reads in foreign media (DOC API), shown as no data where GDELT records no country-level diplomatic events. Popularity uses sourced survey data (EAP 3.0 globally; Afrobarometer R9 Q47A for Africa; Arab Barometer VIII Q102 for MENA) when available; otherwise a curated editorial estimate.

How this is calculated
Executive brief generated deterministically from stat dimensions, archetype classification, difficulty context, and trait labels — no LLM. Completeness is bounded by the underlying inputs: some dimensions have no data source yet (e.g. Diplomacy) and Communication is derived from media coverage where available (otherwise shown as no data, still rolling out).

How this is calculated
Country scores are the unweighted average of scored World Bank indicators and curated estimates — the same model used on the nation's own page. Difficulty reflects structural constraints on governing this nation, independent of the current leader, and is used to compute the Difficulty-Adjusted Score.
