Overview
Understanding GDP calculation, its limitations, and the rationale behind revisions is fundamental for analyzing economic growth, policy formulation, and international comparisons. The accuracy of national income data is crucial for evidence-based policymaking.
National Income Accounting refers to the methods used to measure a nation's economic activity, primarily Gross Domestic Product (GDP). GDP base year revision is a periodic exercise undertaken by national statistical agencies to update the reference year for calculating constant price GDP, incorporating structural changes in the economy, new data sources, and improved methodologies to reflect the economy more accurately.
