DATA COLLECTION STRATEGY
The NBS permanent field staff carried out the data collection during the survey year. The household head or a responsible adult in the household gave information about his household generally. Data collection was carried out in September 2005.
TRAINING
Three levels of training were conducted before the fieldwork. Training of the trainer (TOT) was conducted for the members of the Technical Sub-committee. Twenty trainees who were trained at the first level training later handled the second level training held in the six geo-political zones of the country. During the second level training, 117 participants comprising zonal controllers, state officers and field officers of the National Bureau of Statistics were trained. The third level training took place in each of the 36 states capital and FCT where a total of 1,067 Enumerators and Supervisors of the National Bureau of Statistics were trained.
FIELD ORGANISATION
Listing exercise was done in two weeks. Thereafter, ten export farming housing units (EFHUs) were selected for coverage.
The enumerators and field officers of the National Bureau of Statistics administered the holding questionnaire to all qualified agricultural export commodity farmers in the selected Enumeration Areas in all the states of the Federation and the Federal Capital Territory.
SUPERVISION/QUALITY CHECK
Two phased quality checks were carried out to ensure high quality data. The first phase quality check on holding questionnaire was conducted in September 2005. The zonal and state-based quality checks were earlier carried out by the NBS officials in all states of the federation. During the exercise, the officers skim-checked and spot-checked the listing forms and holding questionnaires in selected enumeration areas. Farmers were randomly selected and visited on their farms to authenticate the entries made by the enumerators. The headquarters-based quality check exercise was also carried out from 17th t0 22nd September 2005 by the Technical Committee.
DATA RETRIEVAL/STORAGE
All the questionnaires were retrieved from the field by the enumerators and submitted at the NBS sub-offices. Subsequently, the questionnaires were batched according to enumeration areas and taken to NBS state offices and later to the zonal offices. All the questionnaires were finally submitted at the NBS headquarters in Lagos.
