According to the site:
The seminar should contribute to the development of tools to help people transform statistics into knowledge and decisions. A first condition for statistics to be used this way is that relevant statistics become known, available, and understood by wider audiences. The seminar is held in the context of the Global Project on “Measuring the Progress of Societies”. It should contribute to one of the goals quoted in the Istanbul Declaration: "produce a broader, shared, public understanding of changing conditions, while highlighting areas of significant change or inadequate knowledge".We use lots of tricks to help people understand what's happening, such as maps that summarize statistics, or drag-down menus to help people find, for example, how their local school matches up with other schools. The end result is helping people make sense of their world.
