Abstract
Household Income Survey (HIS) is one of surveys conducted by the
Department of Statistics, Malaysia (DOSM). The survey was conducted for the
first time in 1973 and subsequently carried out twice every five years, two
surveys in each period of the Malaysian Development Plan. The main aims of
HIS was to measure the economic well-being of the population, collecting
information on household income distribution patterns according to various
socio-economic features and providing basic data for calculating Poverty Line
Income (PLI). Household income and poverty statistics are used for policy
formulation and development plans especially for poverty eradication
strategies and income distribution programs. This paper aimed to describe the
sampling methodology used in designing HIS 2019 in Malaysia. In addition,
this paper will emphasize on enhancement made in HIS 2019. A two stage
stratified random sampling was adopted in the survey. The sampling frame
was stratified by administrative district and urban/rural localities. The Primary
Sampling Unit (PSU) is Enumeration Block (EBs) based on the information from
2010 Population Census. A total of 11,529 EBs were selected from the total EBs
in Malaysia, where 7,557 and 3,962 EBs was selected from urban and rural
areas respectively. The Secondary Sampling Unit (SSU) is Living Quarters (LQs)
within the selected EBs. On the average, eight LQs were randomly selected
from each selected EBs. All households within the selected LQs were included
in the study. Sampling methodology is one of the critical success factors of a
survey. Hence, a robust sampling methodology was used in executing this
survey to ensure the representativeness of the study, thus will provide reliable
findings for users particularly policy makers.
