As a United Nations agency, one of ITU's roles is to identify, define, and produce international official statistics covering the telecommunication/ICT sector. This is in line with other specialized agencies that produce statistics covering their respective field of operations and forms part of the global statistical system of the UN.
ITU collects telecommunication/ICT data for about 200 economies worldwide. These can be divided into three key sets of data:
- Telecommunication/ICT infrastructure and access data collected annually through two (one short and one long) questionnaires. These indicators are defined in the Indicators Handbook.
- Price data collected through an annual questionnaire. Price indicators are defined in the Indicators Handbook.
- Data on access to and use of ICTs by households and individuals, collected annually through a questionnaire. These indicators are the core indicators on access to, and use of, ICTs by households and individuals as defined by the Partnership on Measuring ICT for Development's core list of indicators.
For more information on each one of the questionnaires, see the table below.
