Series Information
The Department of Census and Statistics (DCS) conducts the Household Income and Expenditure Survey (HIES) under the National Household Survey Programme. The HIES had been conducted in combination with Labour Force Survey named as Labour Force and Socio-Economic Survey till 1990. DCS first initiated the HIES as a separate survey in 1990 and since then it has been continued once in every five years till 2006/07. In response to the rapidly changing economic conditions the DCS decided to conduct the HIES once in every three years starting from 2009/10 which enabled to monitor the income and spending patterns in the country far more frequently.
Generally the HIES is conducted over a period of 12 consecutive months to capture seasonal variations of income and expenditure patterns in Sri Lanka. The HIES 2012/13 is the eighth in its series.

Abstract
Main objectives of the Household Income and Expenditure Survey are:
i. To measure levels and observe the changes of living conditions of individuals and households
ii. To estimate household income and expenditure
iii. To compute several important poverty indicators
iv. To provide information to calculate price indices
v. To analyze the impact of social protection transfers
vi. To provide information on different living standard measurements.

Sampling
Sampling Procedure
Sample design of the survey is two stage stratified and the Urban, Rural and the Estate sectors in every district are the selection domains. Thus the district is the main domain used for the stratification. The sampling frame is the list of housing units prepared for the Census of Population and Housing (CPH) 2011.
Primary sampling units (PSUs) are the census blocks selected at the first stage selection and the sampling frame, which is the collection of all the census blocks prepared in CPH 2011is used for the selection.
Secondary Sampling Units (SSUs) or Final sampling units (FSUs) are the housing units selected at the second stage from the 2,500 PSUs selected at the first stage. From each PSU, 10 SSUs (housing units) are systematically selected giving each housing unit in the PSU an equal chance to be selected for the survey. The total sample of size 25,000 housing units results at the end of the sampling process and this sample represents the whole country in different probabilities depend on the different sample sizes allocated for the selection domains.
Allocation of the number of PSUs or determining the sample sizes for the districts is made proportionate to the number of housing units and the standard deviations of the mean household expenditure values reported in the respective districts in previous surveys (Neymann Allocation). Sector allocation of the district sample is made proportionate to the square roots of the sizes of the respective selection domains (Urban, Rural and Estate sectors in the district). The sample of PSUs within the selection domain is equally distributed among the 12 survey months and the monthly sample too is equally dispersed among all the weeks in the month assigning a specific week for each PSU for the survey activities.
