1Data source:
Industrial Statistics Directorate conducts annual survey applied a comprehensive enumeration method since it covers all industrial operating establishments in this sector. It issues reports including data and key indicators of extraction (except oil) and manufacturing industries by sector (public, mixed and private). It is worth to be noted that attempts have been taken place since the 1950s in Iraq to classify types of industries. The reports have being issued as time series form since 1950s.
Large industries classified as large since they use (30 or more) workers. The survey objective is to provide user-friendly detailed data on industrial activities following international recommendations in industrial statistics field.

Statistics Directorate to be checked again according to the validation rules applied to be valid to data entry and revision operation by the software of the system adopted in the directorate to produce the outputs then the report.
Work duration: 3 months

3Definitions of concepts and indicators

Manufacturing rate: the percentage of gross value of inputs to gross value of production.

Inputs: total value of Raw materials + total value of packaging materials + total other commodity inputs +service inputs.

Outputs: includes value of final production + uncomplete production + returns of employing for others + commercial activity.
4Computation methods: many of analytical indicators are computed to get knowledge on the situation of industrial sector and to set plans and strategies according to the following functions:
Employee's productivity from production = Production value/number of employees
Value added = Revenues – inputs
Employee's productivity from value added = Value added /number of employees
= Production value / wages
= Value of inputs / No. of employees
= Wages / No. employees
= (Value of inputs / value of production) 100*
= (Current year/ Previous year-1)*100
Dinar productivity of wages
Average share of employee of inputs
Average annual wage per employee
