Tonga Labour Force Survey 2018 (TLFS 2018)

As evidenced by the 2018 Labour Force Survey Report Survey Solutions software was used for data collection in Tonga:

Data Processing activities for the TLFS 2018 involved various stages, which include: Data was firstly controlled using Validation build into the CAPI questionnaire with Survey Solutions to check consistency, out of range, errors and others. This enables the interviewer to do the entry from the field at the time of interview and these validation checks alert them if some response is wrong.

The secondary was the real-time checking done by the supervisors and headquarters during fieldwork in order to check consistency within a few questions like the household’s income and the individual member’s source of income, needs and availability and some other section like transport, education, and health.
