# Research GDP by Country

Gross Domestic Product is the single most important measure of a country's economic size and health. Whether you are researching emerging markets for investment opportunities, comparing developed economies for business expansion, or studying economic development trends, GDP data is the starting point for any macroeconomic analysis.

The indicator skill retrieves GDP data for any country and time period, while compare_countries lets you put multiple nations side by side. You can track GDP growth rates, compare absolute GDP levels, and study how economies have expanded or contracted over decades. The data comes from authoritative sources like the World Bank.

This serves investors evaluating country risk, businesses planning international expansion, economists studying development patterns, policy analysts comparing government effectiveness, and students learning macroeconomics. GDP data provides the foundation on which all other economic analysis is built.
