What does Gross Domestic Product (GDP) represent?

Gross Domestic Product (GDP) represents the total monetary value of all final goods and services produced within a country's borders over a specific period, typically a year. This comprehensive measure helps to assess the economic performance and health of a country, reflecting how productive the economy is.

Option A accurately captures the essence of GDP, as it encompasses all goods and services, providing insights into the economic activities of the nation. Tracking GDP allows analysts and policymakers to understand economic growth, make international comparisons, and formulate fiscal and monetary policies.

Other options refer to different economic concepts. The total income of a country's residents pertains to Gross National Income (GNI), which factors in income earned by residents from investments abroad. The total number of unemployed individuals reflects unemployment rates, which provide insights into the labor market but are not encompassed within GDP. National investments and savings relate more to capital formation and the financial aspects of the economy, rather than the total output measured by GDP.
