Economic statistics’ is used in its narrow definition, as statistics produced by official statistical agencies and derived from direct surveys or from Government administrative records. Economic statistics concern households, businesses, government and nonprofit institutions, their reactions to changes in the economic environment and interactions with each other. They are shown as values and quantities and deal with production, distribution, the use of factors of production, and the prices at which they are bought and sold. Economic statistics are essential to compile the national accounts. They are presented typically in terms of the activity of the agents to which they relate or in terms of the product produced, sold, or consumed. These presentations are embodied in international classifications used by most countries and developed at the request of the United Nations. Economic statistics are derived form either economic censuses or from administrative registers.
