Why do we need this compilation guide?

At its thirty-ninth and fortieth sessions in February 2008 and February 2009, the United Nations Statistical Commission (UNSC) adopted the System of National Accounts 2008 (SNA 2008) as the international statistical standard for national accounts and encouraged Member States, regional and sub-regional organisations to implement the standard and support all aspects of the implementation of the updated SNA 2008. The SNA 2008 guidelines were produced under the joint responsibility of the United Nations (UN), the International Monetary Fund (IMF), the statistical office of the European Union (Eurostat), the Organisation for Economic Co-operation and Development (OECD) and the World Bank (WB). Countries are encouraged to use the SNA 2008 as the framework for compiling and integrating economic and related statistics, as well as for national and international reporting of national accounts statistics.
