  • Real GDP
    Total value of final goods and services produced, calculated using constant base year prices to isolate changes in production quantity.
  • Base Year
    Reference period whose prices are used for calculating real GDP, allowing consistent comparison across different years.
  • Current Prices
    Market values in effect during the year of production, used to compute nominal GDP and reflect inflation effects.
  • GDP Deflator

  • Inflation Rate
    Percentage change in the GDP deflator from one year to the next, indicating the rise in general price levels.
  • Final Goods
    Products and services purchased by end users, ensuring no double counting in GDP calculations.
  • Expenditures Approach
    Method of calculating GDP by summing consumption, investment, government purchases, and net exports.
  • Quantity
    Number of units of each good or service produced, multiplied by price to determine GDP contributions.
  • Chain Weighted Prices
    Technique averaging prices over time to address changes in relative prices, improving real GDP accuracy.
  • Net Exports
    Difference between a country's exports and imports, included in GDP to reflect international trade impact.
  • Government Purchases
