National accounts are a set of macroeconomic statistics which are key in understanding the workings of an economy. They are crucial for macroeconomic analysis, important for decision making in economic planning and are also used for international comparability. They provide information on the economic transactions between different economic agents in an economy and with the rest of the world. Compilation of these accounts is based on the System of National Accounts (SNA), which is the internationally agreed standard set of recommendations on how to compile measures of economic activity in accordance with strict accounting conventions based on economic principles. The SNA manual provides various concepts, definitions, classifications and accounting rules that guide the national accounts compilation process in such a manner that provides for international comparison.
