Methodology: The Blomstra Mineral Export & Rent Dependency Index measures how economically exposed a country is to mineral extraction and exports. It combines two World Bank WDI indicators:
  • Ores & metals exports (% of merchandise exports) – TX.VAL.MMTL.ZS.UN
  • Mineral rents (% of GDP) – NY.GDP.MINR.RT.ZS
Each indicator is normalized to a 0–100 score (clipped at 60% and 15% respectively) and then averaged equally. Both indicators are required – countries missing either are excluded. Observations older than 10 years are excluded to avoid stale data (see excluded panel below).
