The Tonga Multiple Indicator Cluster Survey (MICS) was carried out in 2019 by Tonga Statistics Department (TSD) in collaboration with Ministry of Health, Ministry of Internal Affairs – Women’s Affairs and Gender Equality Division and other government ministries as part of the Global MICS Programme. Technical support was provided by the United Nations Children’s Fund (UNICEF), United Nations Population Fund (UNFPA) and Pacific Community (SPC) with government funding and financial support of UNICEF and UNFPA through Ministry of Health. The Global MICS Programme was developed by UNICEF in the 1990s as an international multipurpose household survey programme to support countries in collecting internationally comparable data on a wide range of indicators on the situation of children and women. MICS surveys measure key indicators that allow countries to generate data for use in policies, programmes, and national development plans, and to monitor progress towards the Sustainable Development Goals (SDGs) and other internationally agreed upon commitments. The objective of this snapshot of key findings is to facilitate the dissemination and use of results from the Tonga MICS, 2019. The survey methodology and detailed tabulations based on the data collected are available in the Survey Findings Report.
