Statistics of Household Income and Expenditure and their Distribution
Statistics of household income and expenditure and their distribution presented in this chapter
were obtained from the National Statistical Office.
The National Statistical Office conducted survey on household income and expenditure, the first
time was in
1957
and it was called household expenditure survey. Later, in
1968-69
the survey title was
changed to Socio-economic Survey, which was conducted every
5
years till
1986.
Under an economic
circumstance and rapid expansion of the country, as well as the needs of data for policy planning and
formulation in poverty reduction, NSO has been requested to conduct the Socio-economic Survey every
2
years. When the economic crisis took place in
1997,
NSO conducted special rounds of the SES in
1999
and
2001
to obtain indicators for measuring an impact of the crisis to Thai population. However, since
2006
the SES has been conducted annually, that is, in the year of even number, the module of income,
expenditure and debt will be surveyed, while in the year of odd number only expenditure module will be
surveyed.
The survey covered all private, non-institutional households residing permanently in municipal
areas and non-municipal areas of all regions. However, it excluded people living in transient hotels and
rooming houses, hostels, boarding schools, temples, military barracks, prisons, welfare institutes, hospitals
and other such institutions. It also excludes households of foreign diplomats and other temporary residents.
