National accounts are a set of macroeconomic statistics which are key in understanding the workings of an economy and crucial for macroeconomic analysis and decision making. They provide information on the economic transactions between different economic agents in an economy and also with the rest of the world and are used for international comparison. Evidently, economies are dynamic in nature: they grow, they shrink, they add new sectors, new products and new technologies, and consumer behavior and tastes change over time.
