Statistics Norway has a long tradition of compiling national accounts with integrated Supply and Use Tables (SUT) and providing technical assistance to other countries. The ongoing National Accounts project in Malawi is a component of an Institutional Cooperation project between National Statistical Office (NSO) of Malawi and Statistics Norway. The goal of the project is to contribute to poverty reduction by efficient policy planning based on reliable national accounts figures. The objective of the National Accounts project has been to develop an improved methodology implementing UN’s SNA 1993 and a new, efficient IT technique (SNA-NT) to strengthen the compilation of the National Accounts for Malawi. The first milestone has been integrating Supply and Use Tables (SUT) in the annual compilation process from the year 2002. This paper will focus on the experience from introducing SUT in Malawi and the importance of utilising all existing economic statistics and administrative data sources, such as Crop estimates, Annual Economic Surveys, detailed Government accounts, Tax data, Import and Export statistics, Custom duty and Excise duty, Household expenditure surveys and Consumer price indices. For analysing the Malawian economy, the distinction between “Production for own use, Market production, Government accounts and Non Profit Institution Serving Households (NPISHs) is important and also a detailed industry and product breakdown. Balancing the different data sources in a systematic and well-documented SUT framework has provided important quality checks of the data and enabled more of the important informal economy in Malawi to be included in the national accounts compilation. The improved quality, coverage and timeliness of the national accounts system gives a much better basis for the economic and social policy planning. The SUT compilation establishes a database, which also allows the development of Input-Output Tables in current and constant prices at different levels of aggregation. The input-output tables can give a split between Competitive and Non-competitive imports, which allows study of the importance of imports in general and the dependence of imported products on industry production and components of final demand.
