The NLSS 1995/96 is basically limited to the living standards of households.
The basic objectives of this survey was to provide information required for monitoring the progress in improving national living standards and to evaluate the impact of various government policies and program on living condition of the population. This survey captured comprehensive set of data on different aspects of households welfare like consumption, income, housing, labour markets, education, health etc.

Sample Frame: A complete list of all wards in the country, with a measure of size, was developed in order to select from it with Probability Proportional to Size (PPS) the sample of wards to be visited. The 1991 Population Census of Nepal was the best starting point for building such a sample frame. The Central Bureau of Statistics (CBS) constructed a data set with basic information from the census at the ward level. This data set was used as a sample frame to develop the NLSS sample.
Sample Design: The sample size for the NLSS was set at 3,388 households. This sample was divided into four strata based on the geographic and ecological regions of the country: (i) mountains, (ii) urban Hills, (iii) rural Hills, and (iv) Terai.
The sample size was designed to provide enough observations within each ecological stratum to ensure adequate statistical accuracy, as well as enough variation in key variables for policy analysis within each stratum, while respecting resource constraints and the need to balance sampling and non-sampling errors.
A two-stage stratified sampling procedure was used to select the sample for the NLSS. The primary sampling unit (PSU) is the ward, the smallest administrative unit in the 1991 Population Census. In order to increase the variability of the sample, it was decided that a small number of households - twelve - would be interviewed in each ward. Thus, a total of275 wards was obtained.
In the first stage of the sampling, wards were selected with probability proportional to size (PPS) from each of the four ecological strata, using the number of household in the ward as the measure of size. In order to give the sample an implicit stratification respecting the division of the country into Development Regions, the sample frame was sorted by ascending order of district codes, and these were numbered from East to West. The sample frame considered all the 75 districts in the country, and indeed 73 of them were represented in the sample. In the second stage of the sampling, a fixed number of households were chosen with equal probabilities from each selected PSU.
The two-stage procedure just described has several advantages. It simplified the analysis by providing a self-weighted sample. It also reduced the travel time and cost, as 12 or 16 households are interviewed in each ward. In addition, as the number of households to be interviewed in each ward was known in advance, the procedure made it possible to plan an even workload across different survey teams.
99.5 percent of households (3370 out of 3388).
The weights for the survey were derived taking into account the stratification of the sampling frame and the selection of wards within the strata. See "Sampling Weights for the NLSS" for a detailed discussion on the weights for the survey. Data file sample contains the NLSS weights.
Dates of Data Collection (YYYY/MM/DD)
Mode of data collection
As the leader of the field team and the representative of the Management Unit, the key roles of the supervisor in the survey are as follows:
(1) Overall field supervision, coordination and monitoring of data collection activities. The supervisor is responsible for the quality of information collected in the field. An important part of this task is to coordinate the work of the interviewers assist the interviewers in locating households and ensuring their willingness to respond to the survey. It is also necessary for him to maintain good relations with senior officials and other important people in the communities visited.
(2) Monitoring and evaluation of the quality of field interviews and completed questionnaires, and checking of the data entry printouts. Supervisors routinely observe interviews without telling the interviewers in advance. Based on a set of criteria for evaluating a good interviewer, he immediately checks the interviewer's performance. NLSS Form 2: Interviewer Evaluation is provided for this purpose. After the data are collected, the supervisor checks whether the interviewer's recording is legible, if the skip patterns are followed, and that the interviewer instructions given in the questionnaires were observed. NLSS Form 3: Questionnaire Verification is provided for this purpose.
The supervisor also revisits households on occasion to cross-check some of the information provided by the household. NLSS Form 4: Interview Verification is provided to help to cross-check certain key questions. It is particularly important because the interviewers know that data validation will be done. The supervisor carefully checks the errors found by the data entry program, with the help of the interviewers and revisits the household to correct the errors.
(3) Management of personnel, equipment and vehicles In addition to the field management functions, the supervisor is also responsible for supervising the data entry operator and the driver. He ensures that they work efficiently to provide for smooth implementation of data collection activities and be responsible for the proper handling and care of computer equipment and the vehicle.
(4) Exchange of information between NLSS Management and field teams. As the main channel of communications, the supervisor ensures that any advice or instructions from the Core Management Team is relayed to and followed by the field team and that the
Management Team is informed regularly of the progress of data collection activities.
In order to manage the field work effectively, the supervisor may also have to conduct interviews himself if one of the regular interviewers is ill or otherwise unavailable. So he is always familiar with the content not only of this manual but also of the instruction manuals for the interviewers and the data entry operators.
One of the primary functions of the supervisor was quality control, that is, ensuring the quality of the data that is collected by the interviewers and entered by the data entry operators. To do this, the following specific tasks are assigned to him:
2. Assigning Households to interviewers and finding the selected household
3. Preparation of the questionnaires
4. Scheduling of household interviews
5. Verification of the questionnaire
6. Observing interviews
7. Re-interviewing households
8. Administering the community, price, and facility questionnaires
9. Checking the printouts
In addition to the regular supervision done by the respective supervisors in the field teams there is central core team at the headquarters. The members of these central core units are responsible for the overall management and supervision of the field work. It is the duty of this core team for maintaining the smooth operation of the field work.
Any unresolved problems encountered in the field and other unforeseen problems observed during the field supervision were immediately resolved.
As there were twelve field teams in the NLSS-1995 survey, each team was equipped with a field supervisor for independently conducting their field operation. However, the supervision from the team supervisor was found always not enough for the smooth running of the field work. For improving the quality of the field work almost all teams were centrally supervised during the field work of almost one year. However, some teams were revisited for supervision from the core staffs of the center. For the evaluation of the field work during the central supervision a central supervision form thus prepared were filled in for evaluation for future references and follow-up supervision.
The central supervision of the field work of the field teams were not only done by the central core member staffs but at times the international consultants and the members of the donor also participated in this team work. In addition there were good amount of exchange of national and international practices of doing things and of ideas at the time of the field work. In this way the central supervision in the NLSS-I was found to be unique and very special. Above all it has tremendously contributed in the overall aspect of the NLSS survey.
Type of Research Instrument
A preliminary draft of the questionnaire was first prepared with several discussions held between the core staff and the consultant to the project. Several documents both received from the world bank as well as from countries that had already conducted such surveys in the past were referred during this process. Subsequently the questionnaire was translated into NepalI.
After a suitable draft design of the questionnaire, a pre-test was conducted in five different places of the country. The places selected for the pre-test were Biratnagar, Rasuwa, Palpa, Nepalganj and Kathmandu Valley. The entire teams created for the pre-test were also represented by either a consultant or an expert from the bank. Feedback received from the field was utilized for necessary improvements in finalizing the seventy page questionnaire.
