Real versus nominal value (economics)
Gross domestic product (GDP) is a measure of aggregate output. Nominal GDP in a particular period reflects prices which were current at the time, whereas real GDP compensates for inflation. Price indices and the U.S. National Income and Product Accounts are constructed from bundles of commodities and their respective prices. In the case of GDP, a suitable price index is the GDP price index. In the U.S. National Income and Product Accounts, nominal GDP is called "GDP in current dollars" (that is, in prices current for each designated year), and real GDP is called "GDP in [base-year] dollars" (that is, in dollars that can purchase the same quantity of commodities as in the base year).
List of North American countries by GDP (nominal)
Some countries/regions may have citizens which are on average wealthy. These countries/regions could appear in this list as having a small GDP. This would be because the country/region listed has a small population, and therefore small total economy; the GDP is calculated as the population times market value of the goods and services produced per person in the country.
