This chapter outlines the methodology that guides the empirical approach of this investigation. The research aim is to understand public policies against prenatal sex selection, their evolution and impact on sex ratio imbalances in selected Asian countries by providing a qualitative and qualitative assessment. Three countries and three distinct localities within those countries (Northwestern India, Northern Vietnam and Southeastern part of South Korea) were chosen to serve as case studies for the comparative analysis. This chapter first describes the research methodology used for comparing systems of great diversity making use of the Most Different Systems Design (MDSD). It then highlights the country selection criteria and describes the qualitative and quantitative data that has been employed throughout the investigation. The qualitative data draws from policy files, over 100 key informant interviews, and participant observation during political rallies, which was gathered during field research in South Korea, India and Vietnam. The quantitative analysis is based on secondary demographic data obtained from the national statistic bureaus in the three countries to assess policy impact via a difference-in-difference analysis comparing pre-and post intervention periods in target and control areas. The chapter also describes the research sites, data analysis, data quality and comparability before closing with a short summary.
