Series Information
This is the second Living Standards Survey conducted (VLSS) in Vietnam and it is partially panel with the first VLSS which was conducted in 1992/1993.
Abstract
The first Vietnam Living Standards Survey (VLSS) was conducted in 1992-93 by the State Planning Committee (SPC) (now Ministry of Planning and Investment) along with the General Statistical Office (GSO). The second VLSS was conducted by the GSO in 1997-98. Both VLSS surveys were funded by UNDP and Swedish International Development Authority (SIDA). The survey was part of the Living Standards Measurement Study (LSMS) household surveys conducted in a number of developing countries with technical assistance from the World Bank.
The second VLSS was designed to provide an up-to-date source of data on households to be used in policy design, monitoring of living standards and evaluation of policies and programs. The timing of the second VLSS approximately five years after the first allows analysis of medium term trends in living standards as a large part of the questionnaire is the same in both surveys.
In addition to the purpose of obtaining a comprehensive and comparable data set to the 1992-93 VLSS for policy analysis, the survey also served as a medium for training and improving survey methods and analysis within the General Statistical Office of Vietnam (GSO), the agency in charge of designing and implementing the second round of the VLSS as well as other government agencies involved in social statistics.

Sampling
Sampling Procedure
The survey sample was selected to be representative for the whole country, taking into account available funding, geographical conditions, organizational capacity and staff competence. The sample size was set at 6000 households selected from provinces and cities throughout the country, but excluding islands due to logistical difficulties in traveling and conducting the survey in those locations.
The sample for the 1997-1998 VLSS was primarily selected from the households selected in the original 150 communes/wards of the 1992-1993 VLSS. The sample was increased by 1200 households with these additional households obtained from the sample of the Multi-purpose Household survey (MPHS) which was based on a similar sampling methodology. Replacement households were selected randomly from within the clusters of the survey and used where necessary.
The selection of the original sample of 4800 households from VLSS 1992-1993 followed a method of stratified random cluster sampling. The basic sample frame was obtained from the 1989 Population Census. The sampling procedures took into account that communes or wards are the basic local level administrative unit, and each commune/ward has a number of villages or urban residential blocks. The number of households selected in a given cluster was determined primarily based on the requirements for organization of interview teams and time needed for each household interview on location.
Based on the sampling frame including two lists, list of communes and list of wards (or equivalent administrative units) throughout the country with the number of households in each commune/ward obtained from the 1989 Population Census, the sample of the 1992-1993 VLSS was selected in three steps, independently for urban and rural areas:
Step 1: Random selection of 120 communes and 30 wards throughout the country based on the method of probability proportional to the number of households in those villages or wards. The selection of primary sampling units (communes) was stratified by urban and rural areas based on the results of the 1989 Census that 80% of the population was living in rural areas and 20% in urban areas.
Step 2: Within each selected commune, two villages or urban residential blocks were selected randomly by the method of probability proportional to the number of households as in the first stage of sampling. Thus, 240 villages and 60 residential blocks were selected.
Step 3: Within each selected village or residential block, 20 households were randomly selected by systematic method with equal probability, including 16 official and 4 alternate households.
To eliminate the effect of the seasonal differences, the rotation method of sample was adopted: the 6000 surveyed households were divided into 10 sub-samples and each sub-sample was surveyed for one month.
Sampling procedure is explained in details in the document called "Vietnam Living Standards Survey (VLSS), 1997-98", available in this documentation.

Survey instrument
Questionnaires
The second round of the VLSS used 5 questionnaires: household, commune, price, school and clinic.
- Household Questionnaire: The household questionnaire contains 15 sections each of which covered a separate aspect of household activity.
- Commune/Ward Questionnaire: A completely new commune questionnaire was developed for the 1997-98 VLSS survey with a greatly expanded content. A few questions in the 1992-93 questionnaire were dropped or moved to other questionnaires (see below). The commune questionnaire was administered by the team supervisor and completed with the help of village chiefs, teachers, government officials and health care workers. The questionnaire was administered only in rural and minor urban areas, i.e. communes 37 to 194, corresponding to villages 73 to 388. Some sections of the questionnaire contain village/block level information, while most of the commune questionnaire refers to the commune. The commune questionnaire contains 10 sections.
- Price Questionnaire: Price data were collected in all clusters, both urban and rural by the anthropometrist for 36 food items, 33 non-food items, 6 services, 10 pharmaceutical products, and 7 agricultural inputs. Three separate observations were made and these did not necessarily involve actual purchase. However, it is possible that as the anthropometrist is not a local person, the prices quoted are not the true prices of the locality. This information was utilized in checking unit prices in the consumption modules, and for calculating poverty lines. Price indices utilized for adjusting monetary figures to real values were obtained from the GSO CPI unit. Details on how and where prices were to be collected can be found in the anthropometry manual. The actual locations of price collection were recorded in the questionnaires, but unfortunately not entered in the computer files.
- School Questionnaire: The school questionnaires were implemented by the team supervisor to all schools within the two villages selected within a commune. There are between 1 and 7 school questionnaires filled in per commune.
- Commune Health Station Questionnaire: The commune health station questionnaire was implemented by the team supervisor. The respondent could be the director, doctor or physician’s assistant of the health station.
- Household Questionnaire: The household questionnaire contains 15 sections each of which covered a separate aspect of household activity.
- Commune/Ward Questionnaire: A completely new commune questionnaire was developed for the 1997-98 VLSS survey with a greatly expanded content.
