Thailand Demographic and Health Survey 1987 B Institute of Population Studies Chulalongkorn University ® DHS Demographic and Health Surveys f' Institute for Resource Development/Westinghouse \ THAILAND DEMOGRAPHIC AND HEALTH SURVEY 1987 by Napaporn Chayovan Peerasit Kamnuansilpa John Knodel Institute of Population Studies Chulalongkorn University Bangkok, Thailand Institute for Resource Development/Westinghouse Columbia, Maryland USA May 1988 Preface Since its founding in 1966, the Institute of Population Studies (IPS) has been responsible for a number of national surveys focusing on family planning and the demographic and socio-economic situation in Thailand. These surveys included the National Longitudinal Study of Social, Economic and Demographic Change conducted in 1969/70 and again in 1972/73, the Survey of Fertility in Thailand conducted in 1975 as part of the World Fertility Survey, and the National Survey on Family Planning Practices, Fertility and Mortality in 1979. The Thai Demographic and Health Survey (TDHS), conducted in 1987, represents a continuation of this tradition in survey taking at IPS. At the same time, however, the TDH$ has also broadened the Institute's experience in several ways. Not only is it the largest survey in terms of the number of respondents undertaken so far by IPS, but it is the first large scale survey in Thailand to deal in significant detail with health topics including anthropometric measures of children under 3 years of age and their mother~. Because of the inclusion of health topics, the IPS staff has gained new experience and skills which should prove valuable in the future when new surveys are conducted. The purpose of the TDHS is to provide current and accurate data on fertility, mortality, family planning and selected indicators of health status to be used for program assessment and guidance and for scientific analysis to further our understanding of the demographic and health situation in Thailand. We hope that this report makes a significant contribution to this goal. As comprehensive as the report is, however, it represents only a small portion of the potential information and analysis that can be derived from the data collected by the TDHS. In recognition of this, IPS will undertake two broad further analysis projects during the coming year, both funded by the Population Council. One project will focus on demographic and family planning topics while the other will be concerned with health topics. Each project consists of a set of separate analyses dealing with specific subtopics under the two general project rubrics. Together, the two projects will involve many staff members of IPS and will also draw on colleagues at other organizations with expertise in the relevant areas. Thus the current report should be viewed as just the beginning rather than as the final product of our effort to take full advantage of the valuable data collected by the TDHS. AS with any project as large as the TDHS, the skills and efforts of many qualified and dedicated persons had to be mobilized to carry it out successfully. A list of the TDHS staff is provided as an Appendix of this report and therefore there is no need to repeat their names here but rather to acknowledge with gratitude their collective effort. Special recognition, however, is due Dr. Napaporn Chayovan as the one person who on a daily and virtually full-time basis has guided the TDHS through all its stages from initial formulation to the printing of this report. IPS is indeed grateful to her for her tireless and dedicated efforts. Sincere appreciation is also extended to Prof. John Knodel who has provided valuable advice from the initial stage of the project and devoted a great deal of his effort working with Dr. Napaporn Chayovan on every stage of the project including the data analysis of the report. ii Besides the official staff of the TDHS, many people and organizations have been helpful at various stages in providing assistance and advice. The biggest debt is owed to the Institute for Resource Development (IRD), Westinghouse for providing funding and technical assistance without which the TDHS would not have been carried out. A list of consultants, including those provided by IRD, is included in the Appendix along with the TDHS staff. Each consultant not only provided valuable guidance but did so in a professional and friendly way. We have learned much from them. In addition, we would like to thank the National Statistical Office and the Ministry of Interior for providing information necessary for implementing the sample design. The Division of Nutrition, Ministry of Public Health, kindly lent us equipment for weighing the children. A number of individuals deserve mention for help provided in different aspects of the project. The staff of the USAID office in Bangkok (in particular Edwin McKeithen, Karoon Rugvanichje, and Narintr Tima) provided useful advice and encouragement throughout the course of the project. Mr. Art Wichienchareon at ESCAP helped in transferring the data from diskettes to computer tapes. Ansley Coale, Ronald Freedman, Carl Frisen, Robert Hanenberg, Chintana Petcharanonda, and Nicholas Wright provided useful information or comments that assisted in the writing of this report. Last but not least, Ms. Porntip Sopon deserves our gratitude for patiently typing the many versions that this manuscript went through, often coming in on weekends or staying after hours to ensure that the report would be issued on time.
