Measurement of the nominal value of all goods and services produced in a one year period. This production includes that by United States-owned companies as well as by production plants located in the United States and owned by foreign companies. As GDP increases, there is a tendency for company profits and interest rates to rise as well. Conversely, as GDP decreases, there is a tendency for company profits and interest rates to also decline. These figures are published on a quarterly basis by the United States Department of Commerce.
