Sampling
Each village in Niue was divided into enumeration areas (EAs). EA maps and household lists for each EA were provided by the Department of Justice, Lands, and Survey, and these were updated during the enumeration, so that all households in the country were covered at the time of the census. The household updating process involved identifying changes in the households living in an existing house, vacant/demolished houses, and new houses constructed since 2017. The final updating of the household lists was carried out by staff from the Niue Statistics Office and the enumerators in July 2021.
The Census of Agriculture 2021 was conducted using complete enumeration.
Survey instrument
Two questionnaires were used in the Census of Agriculture 2021:
- household questionnaire
- institution questionnaire
The questionnaires covered 20 out of 23 essential items recommended in the WCA 2020.

- Computer Assisted Personal Interview [capi]
In the Census of Agriculture 2021, data was collected through CAPI using tablets with the Survey Solutions software for both the household and institutional questionnaires. In a few cases, paper questionnaires were also used to collect the data.
The fieldwork involved 15 enumerators, 2 field supervisors, 2 office staff, and 1 cartographer. The IT and data processing specialists, as well as a subject matter specialist were consultants from the Food and Agriculture Organization of the United Nations.
QUALITY ASSURANCE
A pilot census was carried out in selected villages to test the clarity of the questions, the methods of data collection, the effectiveness of the training program for field staff, the completeness of the instruction manuals, the duration of the interview per household and the depth of understanding of the questionnaire by the enumerators.
A small set of tables were produced using data from the pilot census to evaluate the census instruments, quality of data and tabulation software. The results of the pilot census were utilized to make further improvements in the census instruments including the data processing system. There was complete response from all households due to re-visits by enumerators and senior officials of the Department of Agriculture, Forestry and Fisheries (DAFF) to households that refused to answer.
A Post-enumeration Survey (PES) was conducted from 1 to 13 November 2021 in a sample of 1 household from each of the 14 villages, to evaluate coverage and response quality of selected questions.
Data processing
Once a questionnaire was received on the server, two CAPI supervisors logged into the interface and reviewed each case received from the field. Cases were reviewed for outliers, enumerator comments, and completeness. In reviewing each case, the CAPI supervisor approved or rejected the case. If the case was approved, it was stored in the final database. If a case was rejected, it was returned to the enumerator along with supervisor's comments for correction. After this, the checking process was repeated until the case was approved. Upon completion of fieldwork, additional data cleaning checks were performed, including coding of open end (other specify) questions, and numeric outlier checks. Data corrections were made as a result of these checks, and a final clean dataset was produced in SPSS and Excel format. Data was tabulated using SPSS, and quality control was conducted on them, checking the balance of values, noting any missing values, etc., before being finalized.
DATA PROCESSING NOTES
CAPI method ensured direct data capture. A comprehensive array of data validation checks was incorporated into the CAPI data collection system to help enumerators identify possible errors/outliers in the data reported. This was done as the responses were recorded so that enumerators could correct the data on the spot. After an interview was completed by an interviewer in the field, it was synchronized using mobile internet to the data server.
