Regional input-output statistics comprise regional supply and use tables and the input-output tables based on them. The data in the tables improve the precision and add depth to regional accounts data. They describe the structure of production in the regions, relationships between economic activities and the dependence of regions on the product flows in other regions and abroad. The results of the regional input-output survey form an integral part of regional accounts. Product flows described according to a consistent and logical framework add to the content of regional accounts data and enhance their quality. Supply and use tables describe the supply of commodities generated by production and imports in a region and the use of these commodities in the production of other goods (intermediate consumption), consumption as final products, capital formation and exports. The symmetrical input-output tables describe interdependencies between economic activities. Analysis tables derived from them can be used to study the importance of the production and final use of economic activities to regional economy and employment.
