The UNESCO Institute for Statistics (UIS)[1] is the statistical office of UNESCO and is the UN depository for cross-nationally comparable statistics on education, science and technology, culture, and communication. The UIS was established in 1999. Based in Montreal, Quebec, Canada, it was created to improve UNESCO's statistical programme and to develop and deliver the timely, accurate and policy-relevant statistics that can be compared across countries.[2] The Institute serves Member states of UNESCO, as well as inter-governmental and non-governmental organizations, research institutes, universities and citizens, with all data freely available. The Institute provides education data to many global reports and databases, such as: the SDG global database of the UN Stats Division, the Global Education Monitoring Report, World Development Indicators and World Development Report (World Bank), Human Development Report (UNDP), State of the World’s Children (UNICEF). Sex-disaggregated indicators are systematically integrated into all UIS data collections.
