Demographic and Health Survey [hh/dhs]
The Population Change and Family Planning Survey is conducted annually with the purpose to collect information on population, population changes (fertility, mortality and migration), contraceptive used and induced abortion as well.
On 15 February 2007, the General Statistics Office's Director General issued Decree N 1430/QD-TCTK on the Plan of the 1 April 2007 Population Change and Family Planning Survey. This sample survey is conducted annually with the purpose to collect information on population, population changes (fertility, mortality and migration), contraceptive used and induced abortion as well.
Since the Population and Housing Census 1999, there has been a remarkably increasing demand for information on population changes, labour force and contraceptive used. Policy makers, development planners, researchers, international organizagtions and mass media have always requested GSO to provide key data collected from the survey. Survey data has helped the Party and Government agencies at the central level assess the implementation of key population indicators, trend and social economic characteristics of the population.
The purposes and demands of the survey are as follows:
- Collect basic information on population and the change of fertility, mortality, migration;
- Measure the coverage of contraceptive uses, menstrual regulation and induced abortion;
- Collect basic information for calculating national statistics indicators in term of population indicator group.
The above-mentioned information represents the provincial/city, rural/urban and national levels as well.

- All usual residents of the household (who have actually lived in the household or have recently moved to live permanently in the household without distinguishing whether these persons were registered as permanent residents by the police or not).
- Currently married women aged 15-49 (for information on family planning).
- Those who were ever considered as usual residents of the household but died from 29/01/2007 (that is, 1st of last lunar new year - BINH TUAT) to the end of 31/3/2007.

Sampling
Sample Frame
The sample of the 2007 Population Change and Family Planning Survey was a sample used in the 2006 population change and family planning survey, with its units being randomly selected from the lists of enumeration areas (EAs) which were established in the 1999 population and housing census.
Determination of Sample Size and Sample Allocation
To ensure an obtainment of sample estimates representative for provinces, cities, the sample was allocated inversely to population size. As a result, each province had a sample size of about 60 enumeration areas with an average of 100 households per EA. Hanoi and Ho Chi Minh city are the two most populous and complicated cities, so they had a selection of over 70 EAs. Provinces with smaller population size also had a sample size of nearly 60 EAs.
The sample of the survey was a stratified cluster sample, in which each province constituted the main clusters (64 strata) with two sub-clusters within each representing "rural" and "urban" areas. The allocation of sample units in each stratum was done using the systematic random sampling method.
The general weights can be calculated from the following probabilities/weights:
- Design weights (basic weights): depend on probability;
- Coefficients used to adjust weights due to variations in the number of households or variations in the total number of enumeration areas because of lost but not replaced by other ones;
- Coefficients used to adjust weights according to structure of the population (universal) under study (self-weighting).
Survey instrument
Questionnaire used in the 2007 Population Change and Family Planning Survey had three sections:
- General information on population:
- Information of those who were ever considered as usual residents of the household but died from 29/1/2006 (that is, 1st of last lunar new year - BINH TUAT) to the end of 31/3/2007.
- Information on fertility, reproductive health of women aged 15-49 years and above

Team leaders are the force that directly controls the daily task of each enumerator, decides the sufficiency and accuracy of the information collected. Each team leader takes responsibility of 2-3 enumerators.
Supervisors are statistical officers who directly participate in this survey and are organized for all three levels of central, province and district. Supervisors must examine supervision process of team leaders and support them in accomplishing their tasks.
Enumerators conduct interviews and questionnaire recording under strict control and guidance of the team leaders. Apart from the task of checking, rectifying errors in the work of enumerators, team leaders are given the responsibility to check all questionnaires recorded by assigned enumerators before giving to district statistics offices, to make sure that questions are skipped correctly, logical errors are corrected and identification information is recorded sufficiently and exactly as stipulated in the guidance documents.
- Recruitment and training of field workers
Enumerators and supervisors were recruited based on their education, experience and their understanding of the local habits and customs, and on their health. Generally, village men were recruited to work as enumerators and district statistical officials were recruited to work as supervisors. In the remote areas with a scarcity of eligible candidates, enumerators were mobilized from other localities, mainly among district statistical officials.
The training for the fieldworkers was conducted for 3 days. It was separated in two stages. The first stage was the training at the central level. For the first stage, two survey staff from each province participated at the training course in Ha Noi and Ho Chi Minh City in the first half of March 2007. The main training i.e the second stage was conducted for enumerators and supervisors before the fieldwork.
- Fieldwork and quality control
Good preparation and logistical work ensured a good provision of professional knowledge as well as necessary facilities to enumerators and supervisors. They were requested to be present at the right place at the right time and to be prepared to undertake the assigned task.
According to the plan, the survey started from 1st April 2007. Except for some remote areas, the fieldworks were to be completed within 10 days. During this period, every enumerator had to visit each of the households in his/her enumeration area to conduct interviews and fill in the questionnaire. Enumerators had to interview household heads to collect information on each of the household members. They had to interview female household members aged 15-49 years and collect information on fertility and family planning. In case it was impossible to meet the household head, enumerators were instructed to conduct interview with an adult member in that household who could provide the information required.
A strict application of the fieldwork instruction ensured a high accuracy of the collected information. Supervisors were assigned the responsibility for day to day field checks. Apart from the task of observing and checking the work of enumerators, supervisors were given the responsibility to conduct random spot checks to make sure that all enumerators had performed their task with high standards.
After the questionnaires were checked and cleaned at the field, they were passed to the Provincial Statistics Offices. Again, checking was done to ensure that all questionnaires were completed.
Data processing
Data entry and editing were carried out at three GSO's statistical informatics centers (Ha Noi, Da Nang and Ho Chi Minh City). Each center established a computer network to process the survey data. Each network included a server and a number of personal computers. The networks in Da Nang and Ho Chi Minh City were connected with the center in Hanoi.
A number of consistency checks were carried out and this was followed by data edition. As soon as data entry for a province was completed, a list of inconsistencies was printed out for verification and correction, and then data files were updated with these corrections.
Data appraisal
Calculation of sampling errors
In order to facilitate in-depth studies on sample reliability of some key indicators, sampling errors were calculated for the following variables:
Contraceptive prevalence rate (CPR);
Contraceptive prevalence rate (CPR) for modern methods;
Immigration rate;
Total fertility rate (TFR);
Crude birth rate (CBR);
Crude death rate (CDR).
The sampling errors for these variables were calculated for national, urban/rural, and regional levels
