Title	What method is used in the Household Income and Expenditure Survey (HIES)?
Date	2015-12-15
The HIES collects data on sample households over 3 years. The sample is replaced by rotation. Interviewers distribute paper diaries to households each month. Respondents fill in paper diaries writing in income and expenditure items. KOSTAT collects these diaries every month, and aggregates them on a quarterly basis for release. For added convenience of respondents, an e-diary is also available in lieu of a paper diary.
