Agricultural Census [ag/census]
The National Census of Agriculture in Cambodia (NCAC) 2013 is the first census of agriculture to be conducted in the Royal Government of Cambodia (RGC). In the past many years the country had conducted several Censuses of Population and Economic Censuses. There were also data produced from the Administrative Reports of the provincial offices of the Ministry of Agriculture, Forestry and Fisheries (MAFF). But the data provided from these censuses and administrative reports did not include any information on the basic structure of the agricultural holdings in the country. Hence, the RGC fully supports the conduct of the NCAC 2013 through the National Institute of Statistics (NIS) of the Ministry of Planning (MoP) in collaboration with the MAFF.
The main objective of the NCAC 2013 is to provide data on the current agricultural situation in the country that will be utilized by the planners and policy-makers. Specifically, the census data will be useful in:
- Providing sampling frame in the conduct of agricultural sample surveys;
- Providing data at the smallest administrative unit in the country; and,
- Providing data on the current structure of the agricultural holdings with growing of crops activity and/or raising livestock and/or poultry and aquaculture activities in the county.

Sampling
This census used stratified systematic sampling using one-stage. The two strata that were used, were households with large agricultural holdings and households with small agricultural holdings. All large agricultural holdings were interviewed while 5 percent of small agricultural holdings were selected using systematic sampling. Large agricultural holdings are defined in two ways:
- Households with at least 10 hectares and over used wholly or partly for agricultural activities were considered to have large agricultural holdings
- Households with at least 10 cattle/buffaloes/other large livestock and/or at least 20 pigs/goats/other small livestock and/or at least 100 poultry were considered to have large agricultural holdings.
Hence, those households cultivating agricultural lands between 0.03 ha. to 9.99 hectares and/or with large livestock ranging from 2 to 9 and/or with 3-19 small livestock and/or with 25-99 poultry were considered to have small agricultural holdings. These households with small agricultural holdings were subjected to systematic sampling. The sampling rate was 5% of the total households with small agricultural holdings. The sample selection was done at the commune level, which was the domain for this census. Hence, the lowest administrative unit in which all estimated results from SMISAH was produced is at the commune level.
The sampling procedures in choosing the sample households with agricultural holdings were as follows:
- In each commune, number the households with small agricultural holdings consecutively from 1 to the last number.
- Add all these households with small agricultural holdings. The total should correspond to the last number provided in the last household in the commune.
- Then compute 5% of these total households with small agricultural holdings and these were the total sample households with small agricultural holdings for that commune. For example, the total households with small agricultural holdings are equal to 550. 5% of 550 are 27.5 or when rounded off, it will be 28 sample households.
- Divide the total households with small agricultural holdings by the number of sample households with small agricultural holdings. This was the sampling interval (SI). For example, 550/28 = 19.6 or approximately 20.
- Get a random start (RS) between 1 and the sampling interval. For example, if the sampling interval is 20; a random start between 1 and 20 should be selected. Let us say 9 is the random start.
- If between 1 and the sampling interval, a random number has been selected, the numbers of the sample households in the commune are determined using the following series of formulas starting at the random start: RS; RS+SI; RS+2SI; RS+3SI; RS+4SI; RS+5SI; …; RS+(n-1)SI. For example, if 9 is the random start, #9 household will be the first sample; then followed by 9+20=29 will be the second sample household; 29+20=49 will be the 3rd sample household; 49+20=69; 69+20=89; 89+20=109; 109+20=129; 129+20=149; 149+20=169; 169+20=189; 189+20=209; 209+20=229; 229+20=249; 249+20=269; 269+20=289; 289+20=309; 309+20=329; 329+20=349; 349+20=369; 369+20=389; 389+20=409; 409+20=429; 429+20=449; 449+20=469; 469+20=489; 489+20=509; 509+20=429; 429+20=449. In summary, the sample households with small agricultural holdings in the given example will be: 9; 29; 49; 69; 89; 109; 129; 149; 169; 189; 209; 229; 249; 269; 289; 309; 329; 349; 369; 389; 409; 429; 449; 469; 489; 509; 529; 549.
Sample selection was done in the provincial office of the NIS. All NIS/MAFF central census staff acting as the overall supervisor(s) in their respective provinces were the lead person to select the sample households with small agricultural holdings.
For details on the sampling procedure please refer to Annex 1 of the Enumerator's Manual.
Survey instrument
The NCAC 2013 utilizes six questionnaires for the household sector; two of which were used in the core module phase and the other four for the supplementary module phase. A listing form to determine the household whether engaged in agriculture activity undertaken in an agriculture holding with size of at least 0.03 hectare was also included in the household sector. There were separate questionnaires for the non-household sector agricultural holdings as well as non-household aquaculture operators. One questionnaire was self-administered by the village leaders.
Form A - Listing Form
Form B - Basic Information on Agricultural Holding
Form C - Growing of Crops
Form D - Raising of Livestock/Poultry
Form E - Aquaculture Activity
Form F - Relevant Information on Agricultural Household
Form G - Village Questionnaire

The NACS 2013 was undertaken in 2 phases: core module in which the listing of all households in all villages in the country was undertaken in 45 days from 17 April 2013 to 31 May 2013; and, supplementary module phase, which was conducted in 24 June 2013 until 23 July 2013. The first phase interviewed all households (using FORM A) to detemine their involment in agricultural holdings; if involved and qualified (according to definition of agricultural holding), the households were further interviewed using FORM B. Then from FORM A and FORM B, 5% of the total households with agricultural holdings were selected using systematic sampling in every village. These sample households with agricultural holdings were interviewed during the supplementary module phase using appropriate forms (F and C and/or D and/or E). Likewise in all villages, Form G was administered by the village leader.
All non-household sectors like corporation, cooperatives, government institutions, and private institutions engaged and managed in agricultural holding/aquaculture operation during the census reference period were enumerated using another forms or questionnaires.
Data processing
Manual processing of questionnaires verified status of completeness, correctness, and consistency of the data entries. Manual editing and coding were performed by four persons (one supervisor and three processors) all of them from NIS. They participated in editing and coding of many surveys conducted by NIS.
CA data processing refers to all activities through which the census documents undergo at the CA Processing Center to prepare them for tabulation of results.
Data processing at the CA Processing Center covered the processing of the following documents:
· Form A (Listing of Household);
· Form B (Basic Information on Agricultural Holding);
· Form C (Growing of Crops);
· Form D (Raising Livestock and Poultry);
· Form E (Aquaculture Activity);
· Form F (Agricultural Household and Its Socio-Economic Characteristics) and
· Form G (Village Questionnaire)
Data Processing consists of the following activities:
a. Receipt and control of all forms from provincial/municipal office
b. Data entry
c. Key verification
d. Consistency and completeness checking
e. Submission of data files and weekly reports to the CA Director General.
