Input and Output
The Input -output Division was established in 2010 after the Department of Statistics prepared the 2006 Input -output Tables.
Input -output tables are considered a statistical description of economic performance. These tables deal mainly with methods of analysis of subordination and interlacement between different economic sectors.
Through input -output tables, economy is divided into a number of sectors. Knowing that number of sectors and commodities included in the table depends upon the objective of the economic analysis and the desire of the planner on one hand and the availability of statistical data on the other. Correlations of each sector are presented in simple equations, including the resources and uses of each sector. Usually tables are used known as Input -output or supply and use tables.
Tables of inputs and outputs are considering of great importance in analysis, planning and providing decision makers with the data that help them in their decisions.
These tables are concerned with the presentation of mutual relations between different economic sectors, industries with commodities (using the International Industrial Standard Classification of Economic Activities and the Central Commodity Classification) these tables represent a square matrix in which the group of sectors is horizontally placed as productive sectors, as the same sectors are vertically positioned as used sectors.
Hence each sector occupies a row and columns in the matrix where distribution of the sector’s products appears in row to other sectors, while the uses of this sector from the products of other sectors are shown in the column for this sector.
At the beginning in order for forming the input -output tables we must construct supply and use tables, which need a lot of details and then do the different balance between the supply side and the demand side then after reaching the balance stage (supply = demand) which is through the manual balance at the beginning and then moving to the automatic balance (Mathematically) and then converting these tables into square tables (columns = rows) which are input -output tables.
