national income and product accounts

National Income and Product Accounts (NIPA) use double-entry accounting to report the monetary value and sources of output produced in a country and the distribution of incomes that production generates. Data are available at the national and industry level.The example is from the United States but the concept is general, varying mainly in the ways different countries collect taxes. The most recent U.S. report (updated quarterly) is available in several forms, including interactive, from links on the Bureau of Economic Analysis (BEA) NIPA ([1]) page. International norms for national accounting methods are given by the United Nations System of National Accounts.
