The main purpose of the 2016 UDHS is to provide the data needed to monitor and evaluate population, health, and nutrition programmes on a regular basis. Increasing emphasis by planners and policy makers on the utilisation of objective indicators for policy formulation, planning, and measuring progress has increased the reliance on regular household survey data, given the inadequate availability of appropriate information from administrative statistics and other routine data-collection systems. The UDHS provides a comprehensive overview of population and maternal and child health issues, and the data are freely accessible to all stakeholders.
