Tutorials & How-To Guides

1. How to calculate GDP per capita Take a country’s nominal GDP and divide by its population. Example: if GDP is $3.0T and population is 100M, GDP per capita ≈ $30,000.
2. Reading a GDP table Nominal GDP shows current-dollar size; GDP per capita hints at average living standards. Read all both together.
3. Interpreting population metrics Fertility rate and median age signal future labor force size; density and urban share hint at infrastructure and housing pressures.

General Information & Further Reading

• Why population size doesn’t equal wealth: small countries can have high GDP per capita if productivity is strong.
• Aging population challenge: developed countries face shrinking workforces and rising support costs.
• Emerging economies: faster growth can shift rankings over time even from a lower per-capita base.
• Rapid growth: youthful demographics can boost potential output if jobs and infrastructure keep pace.
