In 1993, the statistical work of the United Nations was marked by the completion by the Statistical Commission of the revised System of National Accounts (SNA). The revised SNA was the culmination of a 10-year effort—in which 50 experts in national accounting from 40 countries, as well as international and non-governmental organizations, participated—to improve the basis of national accounts, to extend the scope of the national accounting framework and to harmonize different statistical systems. When adopting SNA in July (resolution 1993/5), the Economic and Social Council recommended that it be widely used in compiling national accounts statistics and in comparing national accounting data.
