Face-to-face [f2f]
The data collection arrangement which was implemented adopted two approaches.
The first approach - the household component - involved using 3 teams to conduct the survey. Each team was made up of one supervisor and four interviewers, and covered 20 Enumeration Areas in a raving manner. A pair of interviewers covered 10 Enumeration Areas, with an average of 2 days allocated to administer the General Household Survey and Private Farmers Questionnaires. Twenty days were given as the period for data collection.

The second approach involved lodgement and retrieval of questionnaires for both NISE and SAS operations. Two officers (1 NBS, 1 CBN) were involved in each State, but Lagos used 6 NBS and 6 CBN officers, while Rivers and Kano used 3 NBS and 1 CBN officers each. Altogether, 480 enumerators and 110 supervisors from NBS as well as
37 CBN staff participated in field survey.

TRAINING
Training for the survey was designed to be at two levels. The first level involved the Training of Trainers (TOT), which was done in 2 days and included the senior officers from the NBS and the CBN. The second level training was undertaken at the State level for the field staff (supervisors, enumerators, State officers and zonal controllers). This exercise covered a period of 3 days.
The training sessions included classroom teaching, power-point presentations, mock interviews, role playing, field practice and home exercises. The TOT was comprehensive and efficient, with the overall aim of collecting good quality data.


QUALITY CONTROL AND RETRIEVAL OF RECORDS
As part of efforts to ensure reliable results, a quality control programme was adopted during the data collection stage. There were three layers of supervision involving - the supervisors at the first layer, a combination of NBS and CBN State officers and Zonal Controllers at the second, and NBS headquarters staff at the third.

Eight quality control instruments were also developed. NBS and CBN staff reported on the supervision and monitoring efforts during the period of the data collection. Retrieval of records was implemented in two stages. The first level coincided with the second layer of supervision and monitoring, while the second level was undertaken by NBS headquarters staff. Furthermore, a mop-up exercise was done by NBS State officers for 2 weeks after the scheduled period of data collection, due to low response rate of the NISE and SAS survey questionnaires in the field. The retrieval position of General Household Survey and Private Farmers and Modern Holding Questionnaires are shown in Tables 1.4 and 1.5 respectively. Tables 1.6 and 1.7 reflect the retrieval position of Establishment-based Survey and the System of Administrative Statistics. The retrieval status of both General Household Survey and Private Farmers Questionnaire was very high ranging from 85 to 95 percent. The response rate for NISE sectoral operations varied between 60 to 70 percent. The retrieval rate for the System of Administrative Statistics, which involved more of government establishments, was fairly encouraging. Table 1.8 shows the returns on corporate non-financial.


1.10 REPORT WRITING ARRANGEMENT
The report writing arrangement involved preparation for the report writing, through development of tabulation plans and report writing format or outline. A core team of senior officers from the subject-matter divisions in the NBS and CBN worked together to produce the draft report for finalization.

1.11 WORK PROGRAMME
A joint data production programme by the agencies resulted in the scheduling of activities. Table 1.9 reflects the work programme, which was used as a monitoring guide for the survey. It also helped in programme discipline at each level of activity. The work programme was revised to accommodate delays in the retrieval of completed records in the field, especially for NISE and SAS operations.
Overall, the survey was well managed.
