1. The "Life Saver" for International Students
Lee, a finance student in the UK, had to analyze "Inflation Rates in BRICS countries over the last 20 years."
He tried visiting local statistical bureau websites but failed due to language barriers and inconsistent currency units.
His professor advised: "For cross-country comparisons, always go to World Bank Open Data."
He opened the site, searched "Inflation", selected the five countries, and boom—a standardized comparison chart was generated instantly, ready for Excel export.

5. Conclusion
World Bank Open Data is the digital bridge connecting the world.
It eliminates language and methodological barriers, allowing us to observe global changes on a unified coordinate system. Whether you are a student, a strategist, or just a curious citizen, this is the best starting point to understand the global economic landscape.
Why not directly check data from national statistics bureaus?
Because countries differ in statistical standards (e.g., GDP calculation methods). The World Bank standardizes the data to make it comparable — making it the best choice for cross-country research such as China vs. the United States.
Is the data updated quickly?
Relatively slow. Since it aggregates global data, World Bank indicators generally lag 1–2 years behind (e.g., in 2023, you primarily see complete data for 2021–2022).
Is Chinese supported?
Fully supported. data.worldbank.org.cn is the official Chinese mirror site, with indicator names and interface fully localized.
