The document, one in a series of seven reports from the Value of Children Project, discusses results of the survey in Thailand. The project conducted interviews with 360 married couples in the vicinity of Bangkok. The volume is presented in seven chapters. Chapters I and II discuss the conceptual model, research methodology, and sample characteristics. Chapter III details responses concerning positive and negative values of children including reasons for wanting daughters and sons, reasons for wanting a specified number of children, and general attitudes toward children. Chapter IV presents perceptions of economic costs and benefits of children. Chapter V focuses on family size and family planning including attitudes toward contraception and abortion, family planning knowledge and practices, and the relationship of family size and planning to participant background. Chapter VI describes the value of children and fertility within the social context. The final chapter summarizes findings and makes recommendations for population policy. Responses concerning the advantages of children centered around companionship, economic and general help (especially in old age), and continuity of the family name. Disadvantages included financial costs, concern over the child's health, and the responsibilities of parenthood. Policy recommendations include government insurance or pension plans to reduce parents' dependency on children in old age; a collective approach to social activities to reduce the need for many children; and educational efforts to change family size norms by emphasizing the economic and emotional advantages of a small family.
