Denominator Makes the Hidden Math of Rankings Checkable
An open methodology project publishes sourced, computed data on human outcomes, beginning with a Teenager Outcomes Index covering 125 countries.
Field notes
The project uses a six-step pipeline: assemble a complete matrix, clip indicator extremes at the sample’s 5th and 95th percentiles, normalise, aggregate through named dimensions, rank by two units, and publish the workings. Missing coverage is generally treated as exclusion rather than silently imputed; any modelled imputation is described as row-level and flagged. The current index separates adolescent conditions from future prospects and exposes editable weights and provenance alongside the results.
