Maldives Household Income and Expenditure Survey (HIES 2019) has been spotted here:
The questionnaire was set up such that interviewers could interview households in pairs. It contains a “primary” version in which members have to be listed, and a “secondary” version in which the household module, consumption module or individual interviews could be completed optionally. Files showed predefined check codes that interviewers had to copy to ensure correct linkage and completion.
