PHL-NSO-NDHS-2003-v01
The 2003 National Demographic and Health Survey (NDHS) was a nationally representative survey of 13, 945 women aged 15-49 years and 5,009 men aged 15-54 years.
The main purpose of the 2003 NDHS was to provide policymakers and program managers with detailed information on fertility, family planning, childhood and adult mortality, maternal and child health, and knowledge and attitudes related to HIV/AIDS and other sexually transmitted infections. The 2003 NDHS also collected high quality data on family health, immunization, prevalence and treatment of diarrhea and other diseases among children under five, antenatal visits, assistance at delivery, and breastfeeding.

Sampling
SAMPLING DESIGN AND IMPLEMENTATION
The 2003 National Demographic and Health Survey (NDHS) was the first survey that used the new master sample created for household surveys on the basis of the 2000 Census of Population and Housing. The 2003 NDHS used one of the replicates of the new master sample. The sample was designed to represent the country as a whole, urban and rural areas, and each of the 17 administrative regions. In each region, a stratified, three-stage cluster sampling design was employed. In the first stage, 819 primary sampling units (PSUs) were selected with probability proportional to the number of households in the 2000 census. PSUs consisted of a barangay or a group of contiguous barangays. In the second stage, in each PSU, enumeration areas (EAs) were selected with probability proportional to the number of EAs. An EA is defined as an area with discernable boundaries consisting of about 150 contiguous households. All households in the selected EAs were listed in a separate field operation conducted from May 7 through 21, 2003. In the third stage, from each EA, an average of 17 households was selected using systematic sampling.
For the 2003 NDHS sample, 13,914 households were selected, of which 12,694 were occupied. Of these households, 12, 586 were successfully interviewed, yielding a response rate of 99 percent. Household response rates were similar in rural areas and in urban areas (99 percent).

Among the households interviewed, 13,945 women were identified as eligible respondents, and interviews were completed for 13,633 women, yielding a response rate of 98 percent. In a subsample of every third household, 5009 men were identified to be eligible for individual interview. Of these, 4,766 were successfully interviewed, yielding a response rate of 95 percent.
The principal reason for nonresponse among women and men was the failure to find individuals at home, despite interviewers' repeated visit to the household.

Face-to-face [f2f] interview
The Regional Directors (RDs) were designated as field coordinators in their respective regions.
The Provincial Statistics Officers (PSOs) were responsible for the smooth conduct of the field operation in their respective provinces.
Interviewing was conducted by teams composed of one team Supervisor, one Editor, and four female interviewers and one male interviewer.
The role of the team supervisor included observation of interviews conducted to ensure that the interviewers conducted themselves well, asked the questions in the right manner, and interpreted the answers correctly. She also dids spot-checking to ensure that the correct sample households were interviewed; the supervisors also reviewed questionnaires to make sure that it was complete, consistent and entries were properly recorded. She also had to meet the members of the team daily to discuss performance and give out future work assignments. She also had to solve problems that may crop up during enumeration.
Central office personnel also supervised and conducted spotchecks during the field operation. The whereabouts of the supervisors and the area of assignment of the interviewers were made available at the field offices to ensure close coordination among persons involved in the operation and to be able to locate the interviewers much faster.

The questionnaires for the 2003 National Demographic and Health Survey (NDHS), similar to previous DHS surveys, were translated into six major dialects, namely, Tagalog, Cebuano, Bicol, Hiligaynon, Ilocano, and Waray. The cover of each of the translations differed in color for easy recognition during enumeration and also during the processing stage.
1. NDHS Form 1- HOUSEHOLD QUESTIONNAIRE
The Household Questionnaire was a six-page booklet primarily used in:
- listing all members of the household and visitors;
- recording information on the demographic characteristic of each person;
- identifying women and men who were eligible for the interview. All women aged 15 to 49 years who were listed in the Household Questionnaire of all sample households and all men aged 15 to 54 years who were listed in the Household Questionnaire in every third sample households were eligible for the individual interview.; and
- record household conveniences and other household characteristics.
1. NDHS Form 2 - INDIVIDUAL WOMAN'S QUESTIONNAIRE
The Individual Woman's Questionnaire was used in interviewing all women aged 15 to 49 years who were identified from the Household Questionnaire. It collected information on the following topics:
- background characteristics
- reproductive behavior and intentions
- knowledge and use of contraception
- availability of family planning
- children's health
- feeding practice for children
- women's health
- HIV/AIDS and Sexually Transmitted Diseases (STDs)/Sexually Transmitted Infections (STIs)
- tuberculosis (TB)
2. NDHS Form 3 - INDIVIDUAL MAN'S QUESTIONNAIRE
The Individual Man's Questionnaire contained 233 questions and was used in interviewing all men aged 15 to 54 years who were identified from the Household Questionnaire of the sample households for the male survey. It gathered information similar to that of the Individual Woman's questionnaire though there was an additional section on men's participation in health care and attitudes toward women.
3. NDHS Form 4 - HEALTH MODULE
This form collected information on the health status of the household members, awareness about selected communicable and infectious diseases, utilization of health facilities, knowledge and use of traditional medicines, healing practices and alternative health care modalities, and health care financing. The data were used to assess the health programs of the government.

Data Processing
Data processing involved two stages: manual processing and machine processing.
First stage of processing was the manual editing and coding of questionnaires. This was the major task of the team editor. Field editing was done right after the interview to monitor the interviewer's performance and to edit completed questionnaires in order to ensure that accurate and complete data were collected.
For purposes of operational convenience, field editing is usually done. The interviewers are required to review the entries at the end of each interview. Blank items, which are applicable to the respondents, are verified and filled out. The supervisors are likewise tasked to review the questionnaires for correctness and consistency of entries. Coding, the transformation of information from the questionnaire to machine readable form, is likewise done in the field offices. Before transmitting to the central office, all questionnaires are edited at in the field offices.
Machine processing involves all operations that are done with the use of a computer and/or its accessories, that is, from data encoding to tabulation. Coded data are usually in such media as compact disks and diskettes.
Machine editing is preferred to ensure correctness of encoded information. Except for sample completeness check and verification of geographic identification which are the responsibility of the subject matter division, some imputations and corrections of entries are done mechanically.
Preliminary tabulations are done at the regional offices in order to come up with advance report of the survey results. Further machine processing is done at the central office of the NSO.
