Household
expenditure includes not only household purchasing and payments but
savings, transfers and estimated values of goods and services received
also.
In
HIES the information
related to expenditure was collected on household basis under the
following three
sub-sections of the survey schedule.
-
Expenditure on food.
-
Expenditure on non-food.
-
Expenditure incurred by boarders and domestic servants.
Under
food expenditure, information gathered for 7 consecutive days from Monday
to Sunday with a view to get more accurate data.
For each day, number of persons present for meals and consumption
quantities and values for each and every food item consumed within the
household were reported. Values were estimated according to the market
value for the home-grown food items or items received free of charge. This
information is initially recorded in a separate form by the respondent on
a daily basis under the guidance of the enumerator through three visits to
sample household. This information was later edited where it is necessary
and entered into the survey schedule by the enumerator.
Under non-food expenditure, expenditure values and consumption quantities
of items were gathered and recorded under the relevant major groups such as
Housing, Fuel and Light, Clothing, Health, Education etc.
For each expenditure group, one month, 6 months or 12 months
reference periods were adopted depending on the behavior of the
consumption and expenditure frequencies of the main items in the item
group. Personal expenditure of boarders and domestic servants who live in
the household is reported according to the related expenditure group in a
separate section of the schedule.
Household
size (number of persons usually live in the household) and the activities
of the members are important when studying the household expenditure. Household
sizes vary widely in different domains and survey periods. Therefore, the
household size should be taken into account when comparing household
consumption and expenditure values in different domains and survey
periods. Household size in Sri Lanka has been decreasing continuously
during the past 20 years of survey reference periods.
HIES 2002 results reveal that household size is 4.2 persons per
household in 2002, which is a considerable reduction from 4.5 persons
reported in 1995/96.
