Gross Domestic Product (GDP) is the market value of all final goods and services produced within a country during a given time period. There are two ways to measure GDP:

  • Nominal GDP is the dollar value of production at current-year prices. For example, nominal GDP in 1990, $5,803 billion, is calculated using year 1990 prices for goods and services.
  • Real GDP is the dollar value of production using a given base year prices. For example, real GDP in 1990, $7,112 billion in year 2000 dollars, is calculated using 2000 prices for goods and services.

    • The GDP Deflator measures changes in the overall level of prices for the goods and services that make up GDP. It is simply the ratio of nominal to real GDP times 100. Thus the value for 2000 is 100.

    GDP per capita is calculated by dividing either nominal or real GDP for a given year by the population in that year. These numbers can be thought of as the average share of output per person. The nominal GDP per capita in 1870 was $195, while in 2006 was $44,070; the real GDP per capita for those same years was $2,509 and $37,807.

    The authors have constructed some of these data. There is no doubt that the accuracy of these data varies, and can be different for each the variables and for the different periods. In most cases the earlier the period the less accurate the observations are. It is recommended that users consult the source note before using them for economic analysis.

    The data from 1790 to 1868 are for census years, and from 1869 on for calendar years. See the Source Note on GDP for an explanation.

    These six values are available for any year, or range of years, between 1790 and 2007.
