World Bank Data Review: The Universal Language for Macroeconomic Research

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.
