Data Collection Notes
HIES' are conducted by the Department of Census and Statistics once in 5 years. The questionnaires used in these surveys are very detail and comprehensive in order to capture all the expenditure items irrespective of the amount. In the 1993 survey, on an experimental basis a short questionnaire was used to capture the household expenditure. Therefore the accuracy of the data collected may be slightly different from detail Income and Expenditure Surveys.
