Estimated GDP is 20800.0 USD bn using the expenditure approach.

  • Consumption accounts for 67.3% of GDP. In most high-income economies, consumer spending represents 60-70% of output.
  • Investment represents 16.8% of GDP. Healthy investment levels (15-25%) support long-run growth and capital stock renewal.
  • Government spending is 18.3% of GDP. Note this excludes transfer payments such as pensions and welfare benefits.
  • Net exports are negative (-500.0 USD bn), indicating a trade deficit: the economy imports more than it exports.
  • The largest expenditure component is consumption, consistent with most national account structures.

Next stepTo compare across years, adjust for inflation using the GDP deflator to obtain real GDP. Dividing by population gives GDP per capita, a common welfare proxy.
