Agricultural Survey [ag/oth]
This Private farmer-Livestock/Poultry is the 3rd 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, 2005 and 2006 being the current one. However the Private farmer-Livestock/Poultry is a regular survey of the National Bureau of Statistics conducted on quarterly basis before the collaboration was initiated.
The project produced a series of socio-economic data through households and establishments, and also through the compilation of administrative data sets from public and private institutions. The results and findings from the survey were adequate, credible and current for meaningful monitoring and evaluation of programmes and policies and also for policy formulation at national and sub-national levels. The General Household Survey was designed to provide statistical information on socio-demographic conditions of the members of households in Nigeria.

Sampling
Total sample sizes of 32,850 Farming Housing Units (FHUs) were drawn from 2,190 EAs. In each state, 900 FHUs drawn from 60 EAs were studied. Four hundred and fifty (450) FHUs from 30 EAs were studied in (FCT), Abuja. The listings of housing units in the selected EAs were updated before they were stratified into farming and non-farming housing units. The farming housing units were further stratified into Crop Farming Housing Units (CFHU), Livestock Farming Housing Units (LFHU) and Fishing Farming Housing Units (FFHUs). In each EA, 5 FHUs were studied for crop farming, 5 FHUs were covered for livestock and 5 FHUs for fishery. At each level of selection, housing units were systematically selected using different random start.
All households in the HUs that qualified as farming households were served with relevant private farmers questionnaires.
At Enumeration Area (EA) level the response rate was 91.78 per cent while at the Livestock/Poultry holder level, the response rate was 45.31 per cent
The formula adopted in calculating the design weights for the survey data (sample results) were as follows:
(i) The probability of selecting an EA within a state was obtained by dividing the total number of EAs sampled in a state by total number of EAs in that particular state. Let this be represented by fj. That is,
fj = (Total Number of EAs sampled in a state)/(Total Number of EAs in that particular State)
(ii) Likewise, the probability of selecting an housing unit (HU) within an EA was obtained by dividing the total number of housing units selected in an EA by the total number of housing units (HUs) listed in that particular EA. Let this be represented by fk. That is,
fk = (Total Number of HUs selected in an EA)/(Total Number of HUs listed in that particular EA)
Then the product (fj) x (fk) represented by f is the sampling fraction for each of the corresponding study unit (Enumeration Area) for all the 1,920EAs canvassed throughout the 36 states of the Federation and FCT, Abuja. The inverse of the sampling fraction is known as the design weight and was applied accordingly to all the study units.
Mathematically,
Design weight = ((Total number of EAs in a state)/(Total number of EAs sampled in that particular state)) X ((Total Number of HUs listed in an EA)/(Total Number of HUs selected in that particular EA))
The above value was obtained for each of the 2,190EAs canvassed throughout the 36 states of the Federation and FCT, Abuja. Thereafter, adjustment factors were applied to adjust for the non-responses.
Survey instrument
The questionnaire for the livestock/poultry is a structured questionnaire based on household characteristics with some modifications and additions. The house project module is a new addition and some new questions on ICT.

As earlier stated the data collection exercise involved team made up of 3 interviewers and 1 supervisor. The supervisor assigns EAs to the interviewers and ensures that their job is properly edited at the end of the day.
Prior to the commencement of data collection, training was conducted at two levels; training of trainers and zonal level trainings. This training was to equip trainers and trainees with background information about the survey and what is expected of them. Also, training sessions included classroom teaching, demonstration, mock interviews, role playing, field and home exercises. The crop production Survey a household based exercise, in each state of the federation 3 teams were used comprising of 3 supervisors and 12 enumerators. A team was made up of one Supervisor and four Enumerators. Each team covered 20 Enumeration Areas (EA) for a period of 22 days. A pair of enumerators in a team covered 10 EAs.
Data processing
The data editing is in 2 phases namely manual editing before the questionnaires were scanned. 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 scanned data.
Data appraisal
The Quality Control measures were carried out during the survey, essentially to ensure quality of data. Field monitoring and quality check exercises were also carried out during the period of data collection as part of the quality control measures.
