Series Information
The 2002-2003 Expenditure and Consumption Survey (LECS III) is the third LECS survey conducted in Lao PDR. The first and second LECS were conducted in 1992-1993 and 1997-1998.
Abstract
The Lao Expenditure and Consumption Survey (LECS III) covers the whole of Lao PDR. The statistical unit is the households and the survey covers economic transactions of households to estimate household income, consumption and production and a number of social indicators.
The survey was undertaken from March 2002 to February 2003 (12 months) and it is a survey that NSC plans to conduct every 5 years.
LECS is a multi- purpose survey. Such surveys can be designed in various ways with emphasis on particular issues. In 1992/93 the LECS was combined with a large module of social indicators, Lao Social Indicator Survey (LSIS). The 1997/98 and 2002/03 versions focused on economic activities of the households.
The objectives of the LECS are basically to provide:
- macro estimates for the National Accounts, both private consumption and household investments and income from agriculture and businesses
- the consumption structure (weighing system) for the Consumer Price Index (CPI)
- estimates of labor force
- statistics on access to services
- statistics on nutrition
- statistics on poverty and income distribution
The LECS 3 sample was made up of 8,100 households from 540 villages, 15 households from each, enumerated over 12 months starting 1st of March 2002 and ending 28th of February 2003. The sample was selected using the NSC village list as a sampling frame.

Sampling
Sampling Procedure
A two-stage sampling scheme was used. At the first stage a sample of villages was selected by PPS sampling. The villages were stratified in the following way. Firstly the villages were divided by province, and secondly into urban villages, rural villages with access to road and rural villages without access to road. In all, the village population was divided into 18 (provinces) x 3 (urban/rural classes) = 54 sampling strata. In LECS 2 the sample was allocated equally over the provinces (25 villages in each village). In LECS 3 the allocation was somewhere in between equal allocation and proportional allocation, the number of sample villages in the province ranging from 12 to 48.
The sample of villages in each province was allocated randomly to a survey month so that each survey month had approximately the same number of sample villages.
In the second stage a systematic sample of 15 households was selected in each sample village. The selection was based on a updated list of households in the villages at the time of the survey. The total number of households was less than 15 in four villages. In those villages all households were selected for the survey.

Data Collection Notes
Field Staff, Field Work
The field staff consisted of 180 interviewers organized in 90 two-member teams. 36 supervisors from the provincial statistical offices and 10 central supervisors from head office supervised the teams. The interviewers are permanent staff at the provincial and district statistical offices.
The field work was spread evenly over a 12-month period starting in February 2002, on average 45 villages were visited each month. The teams first duty in the village was to present the survey to the village head and to obtain/prepare a list of households. The team then selected a systematic sample of 15 households according to a predefined procedure.
The completed questionnaires were brought to the provincial statistics office after the survey month and further checked. Data entry was done at NSC in Vientiane.
Each team worked in the field six months during the survey year. The team worked in the villages every second month, the other months they performed other duties in the district or provincial office. Each team thus covered six villages. Transportation to and from villages was done by office vehicles and by public transport (mostly buses). Some of the remote villages required travel by foot for several days.
