This study has been conducted in order to assess the status of women in development in Cambodia, the Lao People’s Democratic Republic, Myanmar and Viet Nam. By reviewing the situation in four countries that share borders, it is possible to highlight similarities and to note common patterns. The study is based on data available primarily from national population censuses and demographic surveys. Detailed data and analysis are provided for each country, and a comparative chapter, including policy implications of the findings, is presented.
