Gross Domestic Product (GDP) measures the total market value of goods and services produced within a country's borders in a year. This definition is central to understanding the economic activity within a nation's economy. GDP encompasses all economic output, reflecting the health of the economy and how well it is performing over time.

When GDP is calculated, it takes into account various sectors of the economy, including consumer spending, business investments, government spending, and net exports (exports minus imports). This comprehensive view allows economists and policymakers to gauge overall economic productivity and compare economic performance across different countries or time periods.

Accessing the total market value helps analysts understand trends, make budgetary decisions, and inform public policy. The focus is strictly on what is produced within the country, whether by domestic or foreign companies; this differentiates GDP from other measurements such as Gross National Product (GNP), which accounts for production by nationals regardless of location.

Other options delve into narrower aspects of the economy or specific measures that do not reflect the overall output of a nation.
