LSIS is a household-based survey that applied the technical frameworks of the Multiple Indicator Cluster Survey (MICS) and Demographic and Health Survey (DHS). It is the first of its kind in Lao PDR. The LSIS was conducted to collect baseline data for the 7th National Social Economic Development Plan (NSEDP) and continued monitoring of progress towards the MDGs. LSIS provides up-to-date information on the social situation of children, women and men covering health, nutrition, education, water and sanitation, marriage and sexual activity, fertility and mortality, contraception, HIV/AIDS, child protection, and use of mass media and information technology.
