The United Nations World Data Forum (UNWDF) is an event of global importance directly related to the 2030 Agenda for Sustainable Development. It provides a space for discussion between different communities of data producers and users. Bringing together different data communities of producers and users, and harnessing the power of technology and other innovative tools are both essential to fulfil the data demands of the 2030 Agenda. Also open to representatives of the economy, science, media, national statistical offices, as well as other administrations and fields, this community can engage in a productive dialogue and identify ways to mobilise the necessary resources for data development. The purpose of the forum is therefore to support the implementation of the 2030 Agenda for Sustainable Development with disaggregated, high quality data. These must be accessible, timely and reliable in order to objectively assess the situation in the various countries and to allow all data producers, including those outside the traditional statistical systems, to present innovative approaches for data compilation, processing and communication.
