IntroductionThe Household Expenditure Survey (HES) was the first conducted in the year 1957/58. Beginning 1993/94 it was carried out an interval of live years and the current survey was undertaken in 2001/9/2010. The survey is covered private households in urban and rural areas.

The main objective of HES was to collect information on the level and pattern of consumption expenditure by households on a comprehensive range of goods and services. This information served as the basis for determining the goods and services to be included in the basket of the Consumer Price Index (CPI). It was also used to represent the expenditure pattern of households in Malaysia.

However, over the years, demand for data from the survey has increased and it is now used for several purposes. HES has becomes an invaluable source of information for government and private sectors,researchers and university students.

Comment

My family has spent the most allocation of income on food, which is RM 1200. We believe that healthy lifestyle is sustained by variety of food. So, we have always buys nutritious food and supplements which have a high cost. Instead, my family only used up RM500 which is the least money among the other categories on recreation. We are living in an urban lifestyle that busy of works and studies.
