Methodology
Active index definitions, component weights, normalization settings, and data-quality rules behind the public MERI model.
Data is temporarily unavailable.
Component inputs are normalized to a 0-100 scale, weighted by pillar, and aggregated into the active MERI definition.
A country can display a composite while remaining unranked if confidence or missing-component rules are not met.
Indicator rows retain source, license, citation, raw-object, quality, and imputation metadata when available.
Observed, licensed, and attributed indicator values.
Inputs are transformed onto the active 0-100 score scale.
Components roll into pillars using persisted methodology weights.
Confidence, missing-data, and imputation rules decide rank eligibility.
Scored countries display; eligible countries receive a public rank.
Active index definitions, model settings, and version history appear when methodology metadata is available.
The public rankings use the newest MERI_READINESS year with non-null composites, currently 2024 in production data.
Some 2025 component rows exist, but broader native source coverage remains below the composite scoring threshold.
Imputed rows are flagged, included in coverage, and credited at lower confidence than observed source values.
Normalized values retain source, license, citation, raw-object, and lineage references when available.
Critical components must be present; imputed critical values reduce confidence but are not treated as fully missing.
Countries with too many missing required components remain display-only until source coverage improves.
Native same-year source rows override bounded carry-forward or adjacent-release imputation when available.

Weights, directions, normalization, and imputation policies appear when component metadata is available.
