U.S. Gross Domestic Product (GDP)
The U.S. Gross Domestic Product (GDP) — the total value of all goods and services produced in the United States — exceeds $29 trillion, making the U.S. the world's largest economy by nominal GDP. GDP growth is the primary measure of economic health, and its relationship to the national debt determines fiscal sustainability.
U.S. GDP is measured quarterly by the Bureau of Economic Analysis (BEA) using three approaches: expenditure (C+I+G+NX), income, and production. The expenditure approach dominates: consumer spending (C) accounts for ~70% of GDP, government spending (G) ~17%, investment (I) ~18%, and net exports (NX) are typically negative (the U.S. imports more than it exports). Real GDP growth of 2-3% is considered healthy; recessions are defined as two consecutive quarters of negative real GDP growth.
