Summary: Since the mid-1990s, 118 countries have carried out one or more Multiple Indicator Cluster Surveys, generating data on key indicators on the well-being of children and women, and helping shape policies for the improvement of their lives. Trained fieldwork teams conduct face-to-face interviews with household members on a variety of topics – focusing mainly on those issues that directly affect the lives of children and women. MICS is an integral part of plans and policies of many governments around the world, and a major data source for more than 30 SDGs indicators.
