Office review is considered a main pillar for the success of any statistical process and a main stage in the process of data preparation. Through this review, we make sure that the researcher is implementing the instructions of data collection and finding and correcting errors according to the set instructions and rules. The office system includes a number of pages through which the Authority official, supervisor or inspector conducts the office review automatically on a PC or tablet during and after the survey.

The process of office review starts with the data collection. He who conducts the review must make sure of the accuracy and consistency of the data. After completing the collection of household information on the first day, the researcher makes an initial review before transferring the data. After this, the official in charge, supervisor, inspector and reviewer can review the data and takes notes on a daily basis.

According to the set timetable for the survey, the inspector can make the final electronic review after the end of the data collection process.

Goals of the review can be summarized as follows:

-Making sure of data accuracy

-Finding and correcting errors

-Easing the burden of automatic collection by the Authority
