Data & methodology

Dataset release: 2026-07-20-worldbank-76-v9baseline. Rules version: 2.5. Each category uses one documented indicator from one authoritative source. Only observations from 2022 onward are accepted. A category is automatically excluded from playable rounds when its 2022+ observations do not meet the configured country-coverage floor.

This experimental build uses 76 World Bank World Development Indicators categories on the known-fast v9 baseline. Each ranking keeps the same contradiction, coverage, tie, and recency checks.
