The data collection was conducted in all provinces throughout the country during 1 - 31 May 2013. There were altogether around 20,000 manpower to carry out the census; comprising of enumerators (agricultural village volunteers) for 15,000 persons, supervisors (agricultural extension officers) for 3,000 persons and the NSO staff for 2,000 persons. The field staff were sent out to interview the household head of all households (listing) in order to find agricultural households and consequently interview for detailed information on agricultural activities (enumeration).
As the data was collected using Tablet, the initial data quality check was done during the fieldwork. The data was sent to the Server for further process on the inspection of data consistency, data accuracy and coverage completion in detail of each household by the fieldwork supervisors. After that the fieldwork supervisors submitted the correctness of the data to the statistical authorities at the provincial statistical office. The final checking for the correctness and completeness of the census data of each province was then confirmed and sent to the Server, and the data was further processed for statistics tabulations and summarized for reporting the census result at provincial level, regional level and the whole kingdom.
After the completion of census field work, NSO has carried out the Post Enumeration Survey (PES) in order to evaluate the quality of census data. The PES was conducted for all households of the selected enumeration areas throughout the country. The Stratified Single-Stage Sampling was applied to this PES. There were four stratums referring to four regions - Central, North, Northeast and South and provinces in each region were represented as sub-stratum. Within each sub-stratum, the enumeration areas were systematically selected; the total samples were 1,280 enumeration areas. After the PES field operation, information between the census and the PES were processed for matching check. And then the process for investigation was to analyse and evaluate errors of the census coverage and the census content, for example the information on the agricultural activity engagement such as livestock, growing rice, planting para rubber, planting permanent crops and planting field crops, etc.
