Income/Expenditure/Household Survey [hh/ies]
The Lao Expenditure Consumption Survey 2002/2003 (LECSIII) was conducted for the first time in 1992/1993, and the second time was 2002/2003 conducted by Lao Statistics Bureau in cooperation with 17 provincial governments, supported by the Swedish International Development Cooperation Agency (Sida). LECSIII was designed to monitor various indicators identified such as GDP and poverty. LECSIII has more questions and indicators than LECS 1997/1998 (LECSII).
The first Lao Expenditure and Consumption Survey (LECS) was conducted in 1992/1993. The second survey was conducted in 1997/1998. This paper describes the third LECS survey (LECS-3), conducted in 2002/2003. The surveys have been conducted as part of the Sida-financed cooperation project between the National Statistics Center (LSB) of Lao PDR and Statistics Sweden.
Data from the surveys are used for a number of purposes, the most important being to produce estimates of household consumption and production for the national accounts. This includes estimating production in household agricultural activities and business activities. Another important use of the data is for the conduction of poverty analyses.
Measurement of household consumption
Household consumption is an important variable in the survey. In order to get accurate measurements of the consumption it was decided to ask the households to keep a diary of their transactions. The measurement of daily consumption through a diary kept by the household puts a heavy burden not only on the households but also on the field interviewers. Many households, especially in the rural areas, need frequent support in the task of keeping the diary. In order to secure an acceptable quality in the data it was deemed necessary to keep the interviewers in the village for the whole month rather than having the interviewers travelling to the villages for repeated interviews and follow-up.
Measurement of household production
Large parts of the value added and labor input concerns household production in agriculture or informal household activities. In order to capture the production three modules were includeded in the LECS: 1) A “light” time diary is used to capture time use for members of the household that are 10 years and above. This enables measurement of labor input in hours in the Lao economy. 2) Two modules on agricultural and household business operations were included. This makes it possible to calculate value added in household production in agriculture and informal business activities.
The 'light' time use diary used in LECS-3 has been developed jointly by Statistics Sweden and ESRC Research Centre on Micro Social Change at the University of Essex. The diary contains 22 pre-defined activities with a pronounced emphasis on economic activities. For some of these activities, the interviewer probes for additional information at the time when the diaries are collected. Those who mark time for worked as employed are asked whether it is as farm worker, in the governmental sector, in the private sector, or something else. Those who mark time for own business work are asked what they do in that business work.

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 es-timate 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 LSB plans to conduct every 5 years. The first and second LECS were conducted in 1992/93 and 1997/98.

The LECS-III is designed essentially as LECS-II with regard to sample design. Experiences from LECS-II have been used to fine-tune the sample design. The number of primary sampling units (PSU) has been increased and the sample size within PSU reduced, giving a somewhat smaller sample in terms of households.
The sample consists of 8100 households selected through a two-stage sample design. Villages serve as primary sampling units (PSU). The villages are stratified on eighteen provinces and within provinces on urban/rural sector. The rural villages are further stratified on villages with “access to road” and “no access to road”. In all, the village population was divided into 18 (provinces) x 3 (urban/rural classes) = 54 sampling strata.
The total first-stage sample consists of 540 villages. The sample is allocated to provinces approximately proportionally to the square root of population size according to population census. The PSUs are selected with a systematic probability proportionate to size (PPS) procedure in each province. Table 1 shows the sample allocation over strata.

The households in the selected villages were listed prior to the survey. 15 households were selected with systematic sampling in each village, giving a sample of 8100 households.
The statistical provincial offices were in charge of the field operations with supervision from NSC. Data on expenditure and income were collected for a whole month based on daily notation of all transaction divided into consumption, agriculture production and household businesses. Interviews with household heads or other household members were held during various parts of the month. At 3
the end of the month households were asked about purchases of durable goods, e.g. furniture, TV, cars, motorcycles, etc., during the preceding 12 months. In the middle of the month one 24 hour pe-riod was selected to record data on time use for all persons in the household ten years and above.
LECS III contains six modules, a diary to record household transactions, household questionnaire and household time use, prices from markets, village questionnaire to village head and a primary school survey. These modules have the following basic structure:
