A key area of ITU's statistical work is related to harmonizing telecommunication/ICT data and developing international definitions, standards and methodologies. To this end, ITU works closely with other regional and international organizations and bodies, including the UN, Eurostat, OECD, the
Partnership on Measuring ICT for Development and experts from countries. ITU’s methodological work to harmonize telecommunication/ICT indicators, develop international definitions and standards is carried out through its
Expert Groups and the
World Telecommunication/ICT Indicators Symposium.
