Aimed primarily at meeting the needs of economists and statisticians, this pamphlet concisely describes the principles underlying the four main sets of macroeconomic accounts statistics, viewed as an integrated system. The four main sets are the national accounts, balance of payments and international investment position, monetary and financial statistics, and government finance statistics. To illustrate the relationships among the sets, the pamphlet covers statistics on transactions, stock data (asset and liability positions), and the linkages between stock data and transactions, as well as some economic statistical series closely related to these accounts. Coincident with the publication of the 1993 SNA, the IMF revised the methodology for balance of payments statistics—also broadening its scope to include the international investment position—and published the Balance of Payments Manual, fifth edition (BPM5; IMF, 1993), also in 1993. Subsequently, the IMF developed the methodology for monetary and financial statistics—published as the Monetary and Financial Statistics Manual (MFSM; IMF, 2000c)—and revised the methodology for government finance statistics—published as the Government Finance Statistics Manual 2001 (GFSM 2001; IMF, 2001).
