1. Introduction
Official statistics provide an indispensable element in the information
system of a democratic society, serving the government, the economy and the
public with data about the economic, demographic, social and environmental
situation. To this end, official statistics that meet the test of practical utility are

statistics has been one of the key goal of SCI and manufacturing statistics is
not an exception.

data gathered from both censuses and surveys should be pass different
process’s steps to be prepared for final users. As the all data in SCI,

surveys hold annually and it also disseminate after finalized the data in
