  • The countries included in this table were selected based on their prominence in global economic and military terms. Specifically, the list comprises the top 50 countries by GDP and the top 50 countries by military strength, resulting in a total of 57 unique countries after accounting for overlaps. North Korea was excluded due to insufficient data across other indicators. Additional scores—covering diplomacy, economic relationships, human development, energy sustainability, and cultural influence—were compiled for these countries to enable comprehensive comparison.
  • The Overall Ranking was determined by calculating the average of all available ranking categories for each country. Only numerical ranking fields were included in this calculation, and any missing data was excluded to ensure consistency and fairness in comparison.
  • The Military Power Index (PwrIndx) is a composite score used by Global Firepower to rank a country’s military strength. It takes into account more than 60 factors, including military resources, finances, geography, and logistical capability.
  • Lower Military Power Index scores indicate more power and higher numbers indicate less power.
  • The Military Power Index rankings will show occasional gaps in the number sequence, as some countries in the index did not make the list of major countries.
  • the United Nations Conference on Trade and Development (UNCTAD), tracks foreign direct investment (FDI) flows globally. The figures represent FDI outward flows, or the total value of direct investments made by a country into foreign economies over a given year. High outward FDI reflects a country’s capacity to project economic influence beyond its borders, develop international business ties, and participate deeply in the global economy. As such, this metric serves as a strong indicator of a country’s global economic presence and relationships.
  • The Diplomacy Index was sourced from the Global Diplomacy Index by the Lowy Institute, and is represented by the number of diplomatic posts each country maintains, indicating the extent of its global diplomatic engagement.
  • The Human Development Index (HDI), created by the UNDP, measures a country’s development based on life expectancy, education, and standard of living (GNI per capita). It ranks countries on a scale from 0 to 1, with higher scores indicating higher development. The HDI is closely related to the concept of “major countries” as it reflects a nation’s economic and social strength, with countries that score higher typically having more global influence, stability, and economic power, which are key characteristics of major players in global affairs.
  • The Energy Trilemma Score measures a country’s ability to balance energy security, equity, and environmental sustainability, highlighting its overall performance in managing and transitioning its energy system.
  • Cultural Influence reflects how globally recognized a country is for its cultural impact, including media, fashion, brands, and modernity—helping identify countries with strong soft power in the world.
  • GDP data for 2024 were polled in Sept 2025 and reflect the historical GDP value expressed in current USD at the time of polling.
