Income/Expenditure/Household Survey [hh/ies]
Household Income and Expenditure Survey 1995-1996 was conducted by the Department of Census and Statistics under the National Household Sample Survey program. This survey is the fourth in the series of income and expenditure surveys conducted once in every five years. As there are few areas in the Northern and Eastern provinces, which are not conductive for this type of survey operation, these two provinces were not covered in this survey.
This survey was done in twelve monthly rounds and was conducted during the period from November 1995 to October 1996 and covered a sample of 21220 housing units. The sample was equally allocated among 12 months to capture the seasonal variation of incme and expenditure values of the households.
The survey provides comprehensive information on household income, individual income, household expenditure, per capita expenditure etc. which are required to study the living conditions and nutritional status of the different segments of population.
Key objectives of the survey
- To identify the income patterns in Urban, Rural and Estate Sectors & provinces

- Average consumption of food items and non food items
- Expenditure patterns by sector and by differnt income levels

Sampling
Sample Design
A multi-stage stratified random sample design was used in this survey. Sectors of the district are the domains for stratification. Master sample frame prepared for Demographic Survey 1994 was used in this survey. There were about 4000 Primary Sampling Units (PSUs) in this frame. From thus frames, sample of 1061 PSU's were drawn for Income and Expenditure Survey 1995/96. From each sampled PSU, 20 numbers of housing units (final sampling units) were drawn to reach a sample of 21,220 housing units. Therefore the weighting factors calculated for Income and Expenditure Survey 1995/96 were based on the corresponding factors of the Demographic Survey 1994.
Sample Allocation
The district and sector allocation of the number of housing units to be surveyed was done proportionate to the square root of the total number of housing units in the district and sector. However selected areas under the urban sector of the Colombo district and the Gampaha district were over sampled to obtain a better representative sample and to obtain weighting factors for computation of Consumer Price Indices.
(Refer Section 1.3 of the Final Report)
Survey instrument
The data was collected by direct interviews based on a special schedule which had three sections:-
(1) Demographic characteristics
(2) Household expenditure (Food and Non-food items)
(3) Household income (Monetary and Non-monetary income)
The demographic characteristics and usual activities of the inmates belonging to the household are reported in the Demographic section of the schedule and close relatives temporarily living away are also listed in the section. Expenditure section has two sub sections to report food and non-food consumption data separately. Expenditure incurred on their own decisions by boarders and servants are recorded in the sub section under the expenditure section. The income has seven sub sections categorized according to the main sources of income.

The field officers (statistical officers) were supervised by the personnel above them in the organization hierarchy such as Statisticians, Deputy Directors & statisticians attach to the Sample Survey Division.
Field Data Collection
Data collection in the field was done by the statistical officers attached to the Divisional Secretariats under each District. The allocated number of blocks for the District that is to be surveyed in the month was equally distributed among the available weeks of the month. A fresh listing of total housing units belonging to the block was done one month before the survey and selection of the SSU's were made from this updated list.
The data collection was done in three visits made to each household. On Monday, the demographic and income related data were collected into the survey schedule and the members of the households were educated to report the consumption of different items in the week. A separate sheet was provided to record the consumption during the rest of the week by the members of the households. A second visit was made in the mid-week to supervise the households recording consumption. The report was collected back after making the necessary corrections in the third visit made on the following Sunday.
