Next, taking into account the rate of response of the last survey, the overall
sample size for sub population j, is as follows:
3
1
3 = 2 × (2.5)

Thus the total sample size, n was calculated by using Equation 2.6.

= ∑ (2.6)
3
−1
Step 2: Carrying out the survey
The survey was conducted face-to-face with respondents, or isi rumah (IR),
in rounds of twelve; one round per month for the whole year, starting from
January. Selected respondents were visited three times or more per week by
interviewers to collect information on demography, income and the
expenditure by classification of goods and services using a set of
questionnaires.
Step 3: Cleaning and validating data
Quality checks were made by experienced officers from the DOSM state
office to detect and correct any error or omission of the data. The review
processes were also implemented for selected household to ensure the quality
of the collected data.
Step 4: Producing results
Analysis of data was done by first separating the expenditures into
respective group and providing a graph that shows the composition of each
group from the total mean of monthly household expenditure by selected
year. Then, the compounded annual growth rate (CAGR) of household
expenditure was calculated and compared. CAGR can be calculated based on
the exponent function as follows:

ln (2.7)
= 0

where
Y current year household monthly expenditure
t
Y previous year household monthly expenditure
o
t period between two subsequent survey year.

3. Result
The main purpose of this paper is to lay out the patterns of Malaysian
household consumption expenditure according to their respective
expenditure group. The data collected are from the year 1993/94 until the
most recent 2016. The table below shows the composition of the mean
monthly household consumption expenditure by expenditure group.
