    Supervision

    Inspection areas comprised many enumeration areas. One supervisor was responsible for one inspection area with 7 to 10 enumerators.

    Roles of supervisor:
    As representatives of the secretary of the Population and Housing Census Steering Committee at each level, he/she supervised and inspected the work carried out in the field. Supervisors served as bridge connecting the Population Census Office at different levels and enumerators. The good performance of the Population Census, with completed and accurate data, depended on the activeness of and attention paid by the supervisors when problems occurred in enumeration areas such as no cooperation from households or locals.

    In case enumerators did not follow survey procedures, or questionnaires or documents were not completed, the supervisors was responsible for reporting and finding solutions on time. Supervisors were seen as team leader for enumerators. They also had to solve technical problems and check the quality of data.

    Data Collection Notes

    During census time, the whole country was divided into 16,000 enumeration areas. The average size is estimated at about 50-70 households per enumeration area. The average household size is estimated at 6 persons per household. In one day, one enumerator could interview about 8-10 households.

    Data processing

    Data Editing

    Editing of census questionnaires was done to guarantee that all questionnaires contained correct answers as instructed.
