Other Household Survey [hh/oth]
The main purpose of the Viet Nam Migration Survey 2004 is to supplement the lack of current understanding about the migration relating to migration decision and results of the different types of moves by migration streams and their relations to regional and national development schemes. Information collected from the survey will form a supplement information source to other available sources (censuses, surveys), and at the same time, provide detailed data on other aspects of the migration process, which are not available at other sources.
The survey focuses on: (a). Model, some streams and types of migration; (b). Cause and results of those moves; (c). Characteristics, including attitude, awareness of the surveyed population in relation to their moves; (d). Characteristics on reproductive health; (e). Those information will be collected for non-migrants in order to find out social-economic differences between migrants and non-migrants. Specifically, the survey aims to the collection of the following data:
· Process of migration including decision of move, number of moves, and process of settling their life in and looking jobs;
· Socio-economic and demographic factors and facilitating factors of migration;
· Consequences of movement of migrants and their family in terms of:
- income and employment
- living conditions and housing
- remittance
- access to social and health services
- life satisfactions and recreation
- adaptation and attitude change
· Comparison of situation of migrants and non-migrants in the destination areas
· Develop policy recommendations on rural development to prevent out-migration, on regional development to divert migration streams to other regions, on information programs to assist those who wish to move, and on health and social services to assist migrants in their adjustment and integration at destination areas.

Household: includes one or more than one persons, having common dwelling and sharing food.
Usual residents: are persons who usually live and have food in the household; or persons recently have moved into the household and stayed stably there for one month or more, regardless of the fact that they have or have not been registered by police office.
Definition of migrants:

Sampling
In total, about 10,000 individual interviews will be conducted, including 5,000 migrants and 5,000 non-migrants. All of them will be in the age group 15-59. To ensure a complete obtainment of the above-targeted number of interviews, it is important to have a good preparation, helping in the determination of enumeration areas with highest migration rates.
The extent to which the sample can be generalized is limited. The main objective of the survey was to understand migration and differentials among migration types, and the survey was not intended to provide estimates that were representative of any clearly defined geographical area. For the five main areas including in the sample design, selection of respondents was not undertaken on the basis of equal probability of selection, either between or within the areas. Furthermore, information is not available to construct sampling weights that would adjust for the unequal probability of selection. Therefore the results for each area should not be interpreted as representing the populations of those areas.
To ensure sufficient representation of different types of migrants, defined here in terms of household registration status, the sampling scheme concentrated on those areas that had the highest proportions of temporary migrants. This means that the results are most likely to represent the areas that are the destinations of high numbers of temporary migrants. Because the non-migrant sample was drawn from the same areas as the migrants, the non-migrants do not represent a cross-section of non-migrants. Rather, they represent non-migrants living in areas that attract large numbers of temporary migrants.

Survey instrument
The survey uses 3 kinds of questionnaire:
- A household questionnaire was administered in each household, which collected various information on household members including
- Identification information
- Information on each of household members: relationship to household head, sex, age and questions used to identify household with migrants or non-migrants;
- Questions for the household as a whole: housing, electricity for lighting, possession of TV, radio, toilet facility, expenses for food, main income source, time to the nearest primary school, secondary school and hospital.
- A Migrant questionnaire includes:
- Part 1: Used to collect information on characteristics of the respondent, such as age, sex, marital status, education level and access to mass media;
- Part 2: Used to collect information on the migration history, such as place of birth, place of residence at age 15, number of moves, and access to urban centre;
- Part 3: Used to collect information on last move, such as the place of residence before the move, reasons of move, decision making process to move, persons accompanying migrant, assistance received, knowledge and utilization of job introduction agency, time for looking for work, difficulties faced, residence registration, and remittances;
- Part 4: Used to collect information on current activity and living conditions, such as: activity status, occupation, industry, time of work, income, expenses, savings, access and use of health services, access to education of children, participation in mass organization activity, and security;
- Part 5: Used to collect information on health, health care, cigarette smoking and alcohol drinking;
- Part 6: Used to collect information on HIV/AIDS, sexual transmitted infections and family planning.
- A Non - migrant questionnaire:
- Except for the exclusion of Part 3, the content of the Form C questionnaire was similar to that of Form B.

Interviewing was conducted by teams of interviewers. Each interviewing team comprised of 3-4 female interviewers, a field editor and a supervisor.
Staff from the district statistical offices and provincial statistical offices were recruited to work as team supervisors, editors and interviewers, and officers from the Department of Population and Labour Statistics of the General Statistical Office were involved in the fieldwork operation as central supervisors. Twenty enumeration teams were evenly divided among the five areas, resulting in four teams in each area. Each team comprised five persons, with one supervisor, an editor and three interviewers. The fieldwork commenced upon completion of the fieldworker training. The fieldwork lasted for a period of nine weeks. Fieldwork was completed at the beginning of November 2004, with the exception of Dong Nai and Ho Chi Minh City where there were some delays due to the pressure of work at the provincial level.
During the fieldwork, the central level supervisors undertook fieldtrips to a range of localities to supervise and help the survey team. The completed questionnaires were handed over regularly to the Central Office with a 20-day interval for office editing and data entry. Based on the office editing and reports from central supervisors, instructions were sent to survey teams in order to overcome errors or problems that occurred during the fieldwork operation.
Data processing
The data-entry programme was developed in CSPRO25 to ensure proper validation of the entered data. The program provided value and range checks of the variables, skip patterns, and relationship checks among designated variables. During data entry, the programme prompted data entry personnel to check the entered value against the value in the questionnaire when inconsistencies were located. Two kinds of prompts were programmed: i). A warning prompt that meant that if the entered value was confirmed the warning could be ignored; ii). A confirmatory prompt that would not allow data to be entered. In the case of a confirmatory prompt, data entry personnel were required to discuss the problem with staff of the Department of Population and Labour Statistics before the prompt could be over-ridden. The migrant household and non-migrant household used the same data-entry programme and have the same data structure.
The data-entry management programme was written in Visual FoxPro. It ensured that data entry and editing worked smoothly and efficiently. This programme was used to monitor survey units and quality of questionnaires; to manage the user data-entry programme; to provide authorization for use of data; to protect against duplication or missing questionnaires in comparison with the selected sample; and to manage data in the LAN environment. It is the interface between the system, data entry personnel and users.
