Data Collection Notes
Trained enumerators and supervisors collected data through face to face interviews from sampled households. The collection of data for the 1st Round of the survey was conducted between October -December 2002. The data collection was conducted on the 2nd Round between January-March 2003 and the 3rd Round during April -June 2003. The data collection on the 4th and final Round was undertaken during July- September 2003. Considering the workload involved and the time taken to retrieve the completed questionnaires from the field, each interviewer was entrusted with the task of canvassing data from 50 to 60 households in 5 or 6 sampled baghs (EA). As the LFS was designed as a quarterly survey much of the field work on the survey was concentrated in the 2nd month of the quarter. Considering the widespread migration of herdsman in the rural areas, it was decided to visit households 2-3 times. These safeguards made it possible to obtain completed responses from 12,787 sampled households in the all 4 Rounds of the survey.
Centralized training of field staff was undertaken for the first time in the LFS in any large-scale survey undertaken by the NSO. A comprehensive manual was prepared which embodied detailed instructions on how to admit the questionnaire and conduct the interviews and the concepts and definitions used in the survey were described in the manual. In cooperation with International Consultants, the NSO WG conducted a centralized training for enumerators and supervisors during the 6th October to 13th October, 2002 in Ulaanbaatar. During the training, under the guidance of WG, the enumerators and supervisors field tested the questionnaire in two districts of Ulaanbaatar city: Khan-Uul and Chingeltei.
Before finalizing the survey instruments, two pre-tests of the LFS, questionnaire and instructions for field operations were conducted in April and July 2002 by the WG of the NSO. The results of the pre-tests were discussed with the Working Group and some modifications in the wording and skip instructions were incorporated. The pre-tests were useful in preparing the draft questionnaire that was submitted to the users for their observations. The 2nd field test was conducted after obtaining the observations of the users and incorporating their suggestions. The 2nd test was useful in identifying a number of deficiencies in the questionnaire. The questionnaire was modified on the basis of the findings, modifications related to the wording of questions, changes in skip instructions, changes in response categories and codes.

Supervision
In each district a team of people was selected – one supervisor for the district, controllers (one controller per 5-6 interviewers) and interviewers (whose number depended on the number of clusters in the region). Coordinator provided overall supervision.
To ensure data quality the LFS and NSO management travelled to 13 aimags and Ulaanbaatar city to monitory the LFS data collection and provide instructions on further proper and due implementation of the survey. The mobilization of NSO staff attached to Provincial Statistical Bureaus had a positive impact as the statistical skills were upgraded through training and exposure to survey methodology including statistical concepts and definitions, classification and coding systems and cartographic work.
