Agricultural Survey [ag/oth]
The Socio Economic Private Farmers (CROP) Survey is the 2nd in the series of collaborative effort of the National Bureau of Statistics (NBS), Central Bank of Nigeria (CBN) and the Nigeria Communications Commission previously conducted in 2004, and 2005 being the current one. However the CROP is a regular survey of the National Bureau of Statistics conducted on annual basis before the collaboration was initiated.
The Socio Economic Private Farmer Survey (CROP) is part of the brainchild of the National Bureau of Statistics (NBS) and is often referred to as a regular survey carried out on annual basis by the NBS over the years. In recent times, starting from 2004, there has been a collaborative effort between the NBS and the CBN in 2004 and 2005 till now the collaboration incorporated Nigerian Communications commission (NCC). The main reason of for conducting the survey was to enable the collaborating agencies fulfill their mandate in the production of current and credible statistics, to monitor and evaluate the status of the economy and the various government programmes such as the National Economic Empowerment and Development Strategy (NEEDS) and the Millennium Development Goals (MDGs).
The collaborative survey also assured the elimination of conflicts in data generated by the different agencies and ensured a reliable, authentic national statistics for the country.

National Agricultural Sample Survey (Private Farmers Questionnaire Survey) samples were derived from the National Bureau of Statistics 2000/05 NISH sample design. The NISH employed a 2-stage, replicated and rotated cluster sample design with enumeration areas (EAs) as first stage sampling units [Primary Sampling Units (PSU)], while the housing units constituted the second stage sampling units [Secondary Sampling Units]. The housing units were the ultimate sampling units for the multi-subject survey.
The Private Farmers' Survey total sample size was 10,950 Farming Housing Units. In each State, the housing units were stratified into Farming and Non-Farming. Five housing units were systematically selected in each Enumeration Area. A sample size of 300 farming housing units was drawn from each State and 150 from FCT, Abuja. The total sample size of 10,950 could provide estimates at national and State levels.
For the NASS (Private Farmers), 5 farming housing Unit (FHUs) were selected systematically after stratifying the housing units into farming and non-farming housing units where all the holders within the selected farming housing units were interviewed using the private farmers questionnaires.
The questionnaire for the Socio Economic Private Farmers Survey (CROP) is a structured questionnaire based on household characteristics with some modifications and additions.

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.
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.
The data processing and analysis plan involved five main stages: training of data processing staff; manual editing and coding; development of data entry programme; data entry and editing and tabulation. Integrated Micro Prossor System (IMPS) and ACCESS software were used for data entry, Statistical Package for Social Sciences (SPSS) and Censuses and Surveys Processing System (CSPro) for editing and a combination of SPSS, Statistical Analysis Software (SAS) and EXCEL for table generation. The subject-matter specialists and computer personnel from the NBS and CBN implemented the data processing work. Tabulation Plans were equally developed by these officers for their areas and topics covered in the three-survey system used for the exercise.
The data editing is in 2 phases namely manual editing before the data entry were done. This involved using editors at the various zones to manually edit and ensure consistency in the information on the questionnaire. The second editing is the computer editing, this is the cleaning of the already enterd data.
The completed questionnaires were collated and edited manually using the following process:
(a) Office editing and coding were done by the editor using visual control of the questionnaire before data entry
(b) IMPS was used to design the data entry template provided as external resource
(c) Ten operator plus two suppervissor and two progammer were used
(d) Ten machines were used for data entry
(e) After data entry data entry supervisor runs fequency on each section to see that all the questionnaire were enterd
(f) Conversion progarm was written to convert the data to spss also provided
