It is due to this greater accuracy that real GDP is favored by economists as a method of measuring economic performance. Countries with larger GDPs will have a greater amount of goods and services generated within them, and will generally have a higher standard of living.
GDP enables policymakers and central banks to judge whether the economy is contracting or expanding, whether it needs a boost or restraint, and if a threat such as a recession or inflation looms on the horizon. By accounting for inflation, real GDP is a better gauge of the change in production levels from one period to another.
Many economists have argued that GDP should not be used as a proxy for overall economic success, much less the more general success of a society.
Like any measure, GDP has its imperfections. For instance, it does not account for the informal economy, does not count care work or domestic labor in the home, ignores business-to-business activity, and counts costs and wastes as economic activity, among other shortcomings.
In recent decades, governments have created various nuanced modifications in attempts to increase GDP accuracy and specificity. Means of calculating GDP have also evolved continually since its conception so as to keep up with evolving measurements of industry activity and the generation and consumption of new, emerging forms of digital and other intangible assets.

The GDP deflator implicit price deflator for GDP is a measure of the level of prices of all new, domestically produced, final goods and services in an economy. Nominal GDP, or unadjusted GDP, is the market value of all final goods produced in a geographical region, usually a country. That market value depends on the quantities of goods and services produced and their respective prices.
Therefore, if prices change from one period to the next but actual output does not, nominal GDP would also change even though output remained constant. In contrast, real gross domestic product accounts for price changes that may have occurred due to inflation. If prices change from one period to the next but actual output does not, real GDP would be remain the same. Real GDP reflects changes in real production.

Keep in mind that nominal GDP can provide an inaccurate picture of economic growth exactly because inflation is baked into the data. The GDP deflator is utilized to adjust the data for inflation, allowing you to understand how much economic output has grown or contracted independent of price changes.
When calculating real GDP, a base year is selected to control for inflation; the real GDP figures capture the quantities of goods produced in different years using the prices from the same base year.
The different real GDP figures from various years reflect changes in volume rather than value. In the first quarter of , U.
This figure, used in the GDP deflator calculation, accounts for the difference between real and nominal GDP in the quarter. Overall, real GDP is a better measure any time the comparison is over multiple years.
One of the limitations of using nominal GDP is when an economy is mired in recession or a period of negative GDP growth. Negative nominal GDP growth could be due to a decrease in prices, called deflation. If prices declined at a greater rate than production growth, nominal GDP might reflect an overall negative growth rate in the economy. A negative nominal GDP would be signaling a recession when, in reality, production growth was positive. Your Privacy Rights. To change or withdraw your consent choices for Investopedia.
