National Accounts are a systematic way of measuring a country's economic activity. They provide a comprehensive overview of a nation's economic performance by tracking the production, consumption, and income generated within its borders. Key components include Gross Domestic Product (GDP), Gross National Product (GNP), and Net National Income (NNI), which help policymakers and economists understand the overall health of the economy. These accounts are compiled using data from various sectors, including households, businesses, and the government. By analyzing this information, analysts can assess trends, make comparisons over time, and inform decisions related to economic policy, investment, and resource allocation.
