Which term describes the total dollar value of a country's final goods and services in a year, adjusted for constant prices?

Real GDP describes the total dollar value of a country's final goods and services produced in a year, while accounting for changes in price levels, thus providing a more accurate reflection of an economy's size and how it is growing over time. By adjusting for constant prices, Real GDP eliminates the effects of inflation or deflation, allowing for better comparisons across different time periods. This makes it a more reliable measure for assessing the true economic performance and growth of a country.

In contrast, Nominal GDP measures the value of goods and services at current market prices without adjusting for inflation, which can give a skewed perspective of economic growth if prices have changed significantly. Gross Domestic Product is a term that encompasses both Nominal and Real GDP, but does not specifically denote the adjustment for inflation. The Consumer Price Index, on the other hand, is a measure used to evaluate the changes in prices of a basket of goods and services over time, rather than the overall economic output.
