That measures everything produced in the United States, whether its by U.S. citizens and companies or foreigners. There are three critical measurements of GDP. Nominal GDP is the basic measurement. It gives an annualized figure. That means it says how much would be produced for the year if the economy kept going at the same rate. <a href="https://web.archive.org/web/20171026035554/https://www.thebalance.com/what-is-real-gdp-how-to-calculate-it-vs-nominal-3306040" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="15">Real GDP</a> does the same, but removes the effects of inflation.

Consumer Spending, which is nearly 70 percent of the total. Business Investment includes manufacturing, real estate construction, and intellectual properties. It is of the total. Government spending is 17 percent. The fourth component is Net Exports. That&#39;s exports, which add to the nation&#39;s economy, and imports, which subtract from it.
